I've been dating this guy for 2 months. I went on a 4 week trip a month after we met and I came back yesterday. All the time I assumed we are exclusive cause before I left I asked him if he's dating other people and he said no and also that he doesn't want me to go out with someone else while I'm gone. I know it wasn't a real exclusive talk (it was just too soon for that back then) but from what he said I assumed we were. While I was gone he told me how much he misses me and that he can't wait to see me again. So I came back yesterday. He asked me if I want to stay at his place and I did and we slept together (we also slept together before I left). He told me how happy he is that I'm back and he made plans what we're going to do in the near future.
So this morning he left early, said goodbye to me very sweetly and went to work. I slept in and now I'm alone here. Well, I just wanted to throw something into the trash in his room when I saw a greeting card with a picture in it lying pretty much open on top of everything. I saw it was him with a girl so I just had to take a look at it. This girl tells him something like "let's get under the covers" and what a great time they had the last weekend and that she can't wait to see him again. She also said Merry Xmas so she sent that card after I left. There also was an envelope (looks like it was from that greeting card) with used condoms in it. It made me feel so sick when I saw that.
I'm totally devastated right now. He told me to call him later today but my first thought was to get my stuff, get out of here and never call him again or return his calls.
Maybe he didn't think we were exclusive yet so he wanted to have some fun before I came back but what about that stuff he told me about not wanting me to go out with someone else? He also said he knows that he has no right to ask me not to out with someone else so he won't try to and that he recommends we figure it out when I get back (the exclusive talk?). So does it look like he didn't think we're exclusive yet?
What should I do now? I'm so disappointed because I already like him so much and he always seemed like he was serious about us. Should I just leave and never talk to him again or should I ask him if we're exclusive? I can't mention that I found sth in his trash, can I? On the other hand I have a right to know since we're sleeping together and it's a health issue.
Thanks
