So I've been dating this girl for 8 months now. She is 22 and I'm 27 so there is some age difference there but not huge. We met at a party once and just talked all night and by the end of the night she and some friends came back to the same place, she started making out with me and next thing I know well things got pretty heavy. The rest of the relationship was very hot and steamy and extremely sexual to the point where I didn't think I could keep it up but it was ok because we didn't see each other too much in the beginning because of her still being in school. Well recently now that its summer and she is out of school she spent a lot more time with me. Ok now honestly I am truly crazy about this girl and cant help the fact that I have never been this crazy about a girl before. Also she seems to feel exactly the same if not even more crazy about me.
Lately though i kinda feel a weird distance. It could be in my head but its something I can sense. We both have been working a ton lately and havent gotten to see each other much lately. She has also been going out with her friends A LOT. Some guys and some girls who i have all met but dont really know all that great. I have never been uncomfortable about giving a girl space and letting her do what she wants but honestly I havent really met a girl i like this much either so maybe it scares me a little. Basically it bothers me that she goes out drinking with her new friends soooo much. She invites me sometimes but rarely. A lot of times she will just stay out till 2am and then call around 2-3 am if she can come over and then she shows up drunk off her butt and sometimes falls asleep trying to wake me up for sex. Its histerical and sad at the same time. I dont like it. Part of me is upset that I just get ignored for her time out most of the time and not invited and the other part is worried she will do something stupid with some guy I dont know or even cheat because Im not there to look after her. It doesnt help that I know some of these guys are in to her. See.. she goes through my phone all the time because she is a bit insecure herself wondering if Im hiding anything and although Im not the type to ever do that I tried it once when she wasnt looking since its fair game and sometimes the guys go too far with what they say. Things like "Cant wait to see you sexy" or "goodnight pretty girl" with the winky face. There are multiple other examples that I saw from all kinds of different guys. None of her responses said anything close to bad back. Usually just like ok or no response at all. I just dont like that guys are talking to her like that and on top of it hanging out without me.
Im just a little lost about how to feel or what to do about it. Cant help that it drives me crazy thinking about some guys at the bar hitting on her. I KNOW she would freak out if the shoe was on the other foot. Ive already stopped talking to flirty friends for this girl and feel stupid now since she is being so hypocritical. She always makes sure to tell me how worried she is some girl is going to steal me away from her while im at the store or with a guy friend hanging out at home. It seems a lot more probable that she would get stolen from me while she is out getting wasted than me shopping or staying in with a buddy.
Edit: I know it sounds crazy and ill probably get responses like "dump her" or "shes cheating" but its hard to know for sure because she is always talking about how in love with me she is to everyone she meets and her friends go on about how she talks about me like Im some amazing catch. She even claims Im the guy she wants to spend her life with and wants to marry me!! Ok, Im real and trying not to be naive. I know talk is just talk until actions are followed but its hard to ignore. She really is an amazing girlfriend other than these things.
