Book Of Likes Faces

I have been seeing this guy for less than a year. We were engaged and took a little break and working on being with each other again. He told his kids that the reason why we broke up is because I'm a "gold digger and would be embarrassed to be seen with me again". That's NOT why we took a break. We were engaged and I wasn't ready to take the step. I asked that we put that on pause and work on the relationship and ourselves more before we get married. He is clinically diagnosed as bipolar and manic depressive. He is on meds now and I thought things were getting better. I want him on the meds for a year before I say "I do". Yet, he is telling me he loves me, we are getting our kids together, he is helping me with chores around the house and things that I need and doing family things together again. I thought we were going in the right direction. I just found this info out from one of his kids over the weekend and I'm really hurt by this. I am NOT a gold digger. He wanted to take care of me when I needed it. I can stand on my own and learning independence again. He is painting me in a bad light with his kids and things are weird now. I really do care about him and I could see a future with him. That's why I want to work on things with him. But now, I really don't know what to do. It's really hurtful to hear this nugget of information. I don't know how to bring this up to him without throwing his kid under the bus because there would be no way of me knowing this without hearing it from the kid. ALSO-I have decided to start my own business and need help putting it together like building things and extra muscle. He said he wants to help me be successful. I ask for his help and he complains about doing "chores" for me and if I don't pleasure his needs, he isn't happy and that I'm using him and that he needs someone better than me to give into his needs.
