<human>: So my bisexual ex is my best friend. We were on and off for a while, and I felt an amazing connection with her. She recently decided, after getting used for sex by her ex fiance, she decided that she's gay. She tried everything she could too hook me up with other women, because she worries for me. 

She set me up with her best friend from a while back. She has some of hobbies like taxidermy, but nothing that would scare me off. What sticks with me is that she cares. She's offered to let me start with her for a while when my roommates move, She won't let me walk away upset, she listens to what I have to say, and she does anything to being a smile to my face.

My problem is that since my ex decided she's gay, and a bit before that, I realized I've never felt the same connection with other women. I've dated and sleep with multiple women, but I just couldn't feel for them. It makes me feel like an asshole that will end up single for the rest of my life.

I don't want to jump into a relationship with this girl because I'm still trying to get myself to feel again, but this is my only option of a place to live until I save up some money. Is there just something wrong with me? Why can't I feel for other girls? I need help and I'm honestly scared.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: I can't feel for anyone since my ex, but the girl she set me up with is about to be my roommate and I don't know what to do.
