I want to leave but I don't know

I've been with my boyfriend for almost 3 years. 5 months ago he moved in with me and we're getting evicted in the spring because we can't afford the rent at all anymore. I know every relationship has its ups and downs and I've seen couples around me fall apart because of a difficult time in life like this, and I want to break up with him. I haven't told him yet because he has no one else to go to and I don't want to hurt him because he's a good guy and I don't want to hurt him like that. But I can't shake the feeling that I've had for a while that I don't want to be with him anymore and I'm very unhappy in my life and in the relationship. But I don't want to abandon him either.<br><br>ETA: I want to say thank you to everyone who has commented. I have taken your feedback into consideration and it has made things very clear for me. I still have a lot to think about but I'm going to do what's best for me. I can't rely on others when it comes to my own life. I also want to apologize for snapping at people, that wasn't right and I should have held myself better.
