Is OTHER wrong in the post ? POST : So for some context I've been with this girl for about 4 years (I'm 21 she's 22) and the relationship has been going pretty bloody well, I've been the happiest I've ever been and she isn't sick of me yet so I think I got keeper.

For the past year and half she has been staying at my friends house wed - fri so rants she can get into the uni base as she live a good 45 minutes away by car ride and she hasn't got the money for fuel to do that trip 3 times a week sometimes 4 and that I totally understand that as fuel is pricey as hell atm.

Now this wouldn't bother honestly as I trust her and I trusted my friend as I've known the guy for almost 10 years but a couple months ago she came to me and told me he confessed that he has feeling for her and I'll be honest this has thrown me into a man child sulk ever since and whenever me or her brings up the topic of her staying there  I take it out on her by neing cold and mean and I know I shouldn't but I just have this bad feeling.

I really don't want my jealousy to destroy this relationship as I genuinely love this girl, Also im think of taking anger management classes as I had that problem as a teen and I don't want to fall back into that mind set again.

Update: had a long talk with my gf about all this and I even showed her this post.

She said she understands why I feel like this as she's had a similar experience, she said she would help me get through it all as long as I talk to her when I feel down and try and be happy as much as I can
