My boyfriend and I been together on and off for about 8 years. We have two boys together and a daughter of previous relationship. The last time we got back to dating again it's when I got pregnant with 19month old boy now. The situation is I don't love him the way I did at the beginning and now I'm just with him for the kids. Our sex lives has deteriorated as 1or 2a month.  I started to have episode of anxiety and depression I'm even drinking medication to control i. But I see the smiles he produces in my babies faces. What should I do?
