Search Results: spoiling a girlfriend

its been 4 year tuff relationship. my girlfriend has always been drinking so much which i don't like from the beginning and i hav been trying to make her stop but its not working.
when ever we fight and not talk to each other she makes sure to do things which hurts me like drinking, smoking up, talking to guys who likes her, socialising with guys and girls whom i hav no idea off, partying and going on trips without me while ill sit in my room and worry about this. she has few friends who have always been a threat to this relationship and influencing her in doing wrong thing and when i ask her to avoid them its a NO but she told she will avoid once out of college she would but no. she also ditched me and went to another city for 4months and stayed with people whom i had no idea off and had fun and partied, drank all the time and lied to me. and when i went to see her der she was busy smoking up and drinking somewhere so i cudn see her and had to return back. when ever i tell her not to drink so much and keep it in limits / avoid few people whom i feel are spoiling her and this relationship/ or not smoke up/ or try to advice her on few things its a very arrogant answer i get from her ' Don't tell me what to do and what not to' she has lied a lot to me and hidden things from me about all this but i still try get back with her every time we fight. and it is always me who takes the initiative of talking to her or getting back to her after a break up while she will ignore me for days and after repeated begging she replies. and from last three months its been more tuff. she has left her house, and stayin with her friends when i told her not to and reconsider it she dint. i supported her for that as well but again she ditched me and went to party with her gfs when i was searching for a house for her to stay. now she is smoking up everyday drinking more and making friends with guys. i know its time to end it. but i would like to kno if i did anythin wrong or suffocate her?
