Should I end my friendship?

For the past year or so, this friend has helped me a lot whenever I was suicidal. I was suicidal a lot though, and it really took a toll on his mental health. We talked about it and stayed friends though, but it was bothering me that it seemed like I was the only one putting effort in to maintain the friendship. So I tried talking to him about it, but he said he’s not going to go out of his way for me anymore, so basically nothing is going to change. He said he still considers me a good friend though? But also said he’s kind of indifferent towards me, which seems like conflicting statements. And I’m not the only one to damage the friendship, he had his part in it too. Right after I broke up with my boyfriend he kind of took advantage of the fact that I couldn’t sleep alone and asked me if I wanted to come over, and after I said yes he added that he wanted to do sexual things. And the friends with benefits thing continued for a long time, and I let it continue because it was the only time he would hang out with me and I needed a friend. He has apologized for that. It just seems like he cares one minute and the next he doesn’t, and I don’t know if this friendship is good for my mental health. I’d just feel bad ending it after he helped me through so much, but he’s not interested in putting effort into the friendship, so what am I supposed to do?
