Input: So this happened about 6 months ago and isn't a huge deal anymore, but it occasionally comes up and i think about it from time to time wondering if i really am an a-hole for it.  Story goes that it was my gf's birthday so i went over to her house so we could celebrate.  As soon as i walked into her room i noticed an opened condom wrapper on the floor.  It couldn't have been one from me because we had never had sex at that point.  I showed it to her and asked why it was there.  She, of course, denied cheating on me and said it probably was an old one that came from under her bed (she has a cat that could have found it and started to play with it).

I wasnt completely convinced and knew i needed to check the trash to be sure there wasnt a condom in there.  She left the room to go do something so i decided i would check.  She was using a plastic bag hung up on her closet door as a trash bag.  So i looked inside and, without having to dig through any trash, i saw a used condom in it.

I was beyond pissed, absolutely sure that she had cheated on me.  I grabbed the condom (a bit gross i know but i was angry and didn't really care) and went downstairs to confront her with it.  She lives at her grandmothers house, along with her sister and her sisters bf.  Her sisters bf ended up coming up the stairs as i was going down and saw the condom i was holding.  He was unsurprisingly confused as to why i was holding a condom and asked who's it was, so i told him "well it isn't mine".  He got that "oh shit" look on his face and went upstairs.  I caught up with my gf and showed her the condom and we ended up going back upstairs to argue about it.

She was mad at me for going through her trash, saying it was a breach of her privacy.  I was mad because i had just found a used condom wrapper on her floor and a used condom in her trash.  She continued denying that she cheated on me and said that it was an old bag that she found in her closet that she decided to use for trash, and that she must have thrown that condom in there as trash the last time she had sex.  I didn't believe her as the chances of finding a used wrapper and condom was too small for me to think it was just coincidence.  Eventually her sister came up and helped us talk through it, telling me that she believed my gf was telling the truth and could tell when she was lying.  So i decided id listen to her and trust in my gf.  But my gf was still mad that i didn't trust her immediately, had went through her trash, and embarrassed her by 'showing' the condom to 'everyone', on her birthday nonetheless.

We moved on from it, as we're still together, but i still wonder if i was an a-hole for what i did or if it was appropriate that i believed she had cheated on me.  My gf has also done some other shitty things that still make me unsure sometimes whether i ever should have believed her or trust her now.
