My girlfriend still has her ex boyfriends clothes despite us being together surely I'm not a cuckhold to want to keep the relationship going despite the given situation?

We’ve been together for a bit over a month now. Yesterday she told me she still has her boyfriend’s clothes with her. Even during our talking stage she would always talk about her ex—what he did to her, ranging from SA’ing her to abusing her. I can resonate with the abuse part because my mum went through that with my dad, but I’m confused. If he really did that to her, why would she still keep his clothes?

I’ve been trying to get her to move on. I’ve spoken to all my friends about it and they say I’m wasting my time and should end it immediately, but I genuinely see hope and a future with this girl. We like the same things and more. Sure, she’s not there emotionally, but we’ve accepted our differences. Over the past week it’s been getting to me, because it feels like she’ll never move on.

As someone who isn’t sentimentally attached to people I’ve been in relationships with, I just feel bored. But at the same time, I can’t stop thinking about her. This is all new to me and it feels like I can’t control my feelings, because this isn’t something I’m familiar with. I’ve told my friends and they keep saying I’m going to end up wasting my time on a girl who will inevitably leave, which is why I never took past relationships seriously. But this one—I feel obligated to. I don’t know what’s making me feel this way.

Anyway, what would you guys advise I do? I don’t want to end it, but at the same time I feel like a filler for her ex-boyfriend. Sometimes when we talk she cuts herself off and cries, saying she hopes I don’t R-word her or assault her, which really shook me. I don’t know what to do.

My friends have ridiculed me a lot, calling me a “cuckold” and a lot of other things for this relationship alone, and it’s slowly getting to me. I’m trying to distance myself slowly and lose feelings, but I don’t want to leave her like that. At least if I’m going to leave, I want to admit it.
