<human>: I live with my boyfriend in a shared house. I (25f) went home over winter break to see my family. When I came back he (25m) had done laundry and there was clothing everywhere, including some girl's clothes in his room that weren't mine (no girls live with us).  First I found pants and a shirt in the room; then about a week later when the next load of laundry came out, underwear and a bra. 

I confronted him and he claimed they are probably a family member's, or else he doesn't know whose they are. Since the laundry room is shared and a lot of cousins and nieces come in and out of the house that is possible, but I just have a vague feeling none of them would wear these clothes, and it bothers me that it is *all* the components of an outfit, not just random miscellaneous articles of clothing. I've stopped asking about it -- it has been weeks since I found it -- but am feeling really resentful and suspicious. I feel like he has no incentive to tell the truth here so why should I believe him? Is he cheating? What do I do?

Give me a shortened version of the text
<bot>: Found girl's clothing in my boyfriend's room after going away for xmas. He claims they are a relative's, and I have doubts. How suspicious should I be?
