My girlfriend and I have been dating for over a year and we are in a commited relationship. I suspect she has cheated on me before but I have no proof. I have caught her making out with other people (sometimes even in front of me) but cant confirm anything more for sure. We have a recurring problem that goes like this... So last night we are hanging out at home, watching TV and drinking. It gets late and I have work the next day so I go to bed. She stays up and continues to drink. I can hear her downstairs making phone calls and she comes upstairs to get dressed to go out. Its about 2am at this time. She says she will be home in an hour and I can tell she is really drunk. She ends up staying out all night getting home in the afternoon the next day. I dont know what happened but to me this not OK. She claims that I am trying to control her and that there is nothing wrong with this behavior. I dont know what to think. I guess I am asking for advice. I have been considering breaking up with her. I dont really want to but I also dont want to live always wondering where she is and what she is doing. Help me out! cliff notes: girlfriend goes out all night. gets drunk. doesnt come home til next day. i dont like it. shes says i am trying to control her. what do you think?
