Leaving a long lasting relationship with 2 kids

Ladies, I have a question. Me and my bf have been together 6 years, this year. We have 2 kids. I'm just not into him anymore. Yes I do love him. It's hard for us to just break up bc I don't want him to be homeless when we break up! But I don't want him anymore. We just don't match. I'm extremely unhappy. HELP!
