Can someone help me in this, like libra men would be good?

This is going to be quite long, last year i met a boy and i liked him from the very start. he was amazingly lush and reallly nice to me, but he was taken. he told me he liked me aswell and he would get with me if he was single but he loves his girlfriend.. and then this one night i was sleeping around his cause he had a house party, and we were both drunk and slept together. he didnt regret it but told me not to tell his gf and i didnt. christmas time his gf dumped him and he was heartbroken he really was. oh by the way i used to be reallllly shy back then i never used to speak to him AT ALL in person just on msn. he said that was the main reason he didnt wanna get with me cause he dont wanna have a quite relationship and stuff.. i still liked him tho and i tried my best speaking to him but i couldnt. and he tried getting back with his ex for 3 months and still liked her after. anyway we both moved on, had a couple of arguments and hated eachother for abit and then 5 months ago we started meeting up again and i got talking and we had sex and he dumped his gf for me and i dumped my bf for him and we got together after a week. and as soon as we went out i started getting shy again so he dumped me and wanted to stay friends for abit so things would get better. and then after 5 days we got back together and i havent been shy since. but we have so many arguments over stupid things.. its usualy his fault but i spose i can get annoying at times. couple of months ago i caught him texting the ex that he used to be in love with saying that he enjoys talking to her and just generaly flirting. now i believe in horoscope fully to be honest, and it says libra men can't help flirting but they barely take it anywere. and its tru he barely liked me the year before when he was with his gf just flirting and stuff. bu i dont like the thought of it. im scared that he will dump me for his ex cause he used to like her so much, he says he doesnt and he liked me alot cause even tho i piss him off constantly hes still with me. and i know but he promised hed stop texting her and he still does it. i have cried infront of him about 6 times cause of it. last time i caught him flirting with her and i cried he even cried too. he said he didnt wanna lose me over something like this. but i just dont understand if he actualy cares why does he still do it when he knows how much it upsets me. i love him too bits and i never wanna lose him. so im trying to make things work out. im 16 btw and he is 17. dont tell me stuff like you dont know what love is cause i do. i really love him more then anything. also hes ex still fancys him and shes the one who keeps starting the flirting. and hhe says he doesnt know that he flirts:S me and his ex used to be mates but we arent now and ive had ago at her about a billion times but shes saying she can do what she wwants. and to be honest i can't trust him with her anymore. i just don't understand why he is doing this to me. he is also saying he hates people telling him what to do yet he always tells me what to do and he is really over protective. and he wont even put me on his msn name even though were going out because he says he doesnt need to put me in his name to prove his love to me. and i know that but i like being in it and he knows that so why cant he just try and make me happy. sometimes i just dont think he cares. and he is always on this computer game called dofus even when im around and he always chooses it over me. and it upsets me that im being compared to a game:(. sometimes hes amazing tho. he says some stuff in person while he is holding me and kissing me that really does make me blush. and i enjoy talking to him. but i dont know what to do anymore:( i know he can get back with his ex whenever he wants and that kinda shows he likes me more cause he is staying with me.. but still i just don't like him flirting. someone please helppp:( some advice...Can someone help me in this, like libra men would be good?
Well, I am a Libra, and I certainly see plenty of the traditional Libra characteristics in myself.





As for this boy in your life, however, I think he is simply immature, and not really serious about any relationship, with either you, or the ex.Can someone help me in this, like libra men would be good?
Wow! Damn! Your question/passage is long. I didn't read all of it, but I read 2/3 of it. So...is he a Libra? To be honest since I am a Libra guy as well, Libras have a natural innate habit of flirting and not only just Libra men. Libra women flirt as well. Flirting for Libras is natural like I said. It's like a syndrome we can't help. Kind of like nicotine and smoking. Even though us Libras flirt, we are loyal to our lovers usually. If you're dating a Libra guy and he flirts a lot, don't take it too seriously unless he intends to cheat on you. I think you just made a mistake going with him. He probably still loves his ex if he keeps going back to her otherwise flirting is natural for Libras as mentioned.
