Financial talk

I am only 24 years old, I got married when i was 19 because I got pregnant I am a mother of two beautiful kids but i just think i don't love my husband anymore. I never go out no where without the kids because i don't like it he gets to go out with his friends every week at least two or three times plus he goes to the gym, but i don't care. He asked me out but I don't feel up to. Well I work M-F from 8AM-6PM as a nanny and i get to take my kids with me, I also go to college so I defenitely want to have a career. At the time I make more money than my husband and we have joints accounts since a couple pf months ago before i used to have savings now i don't have nothing because he over spends Iand but away I never want to have sex with him, I just do it when I don't have any other choice(just so that he stops bothering me) I don't know what to do... P.S. Before when we got together he had a really bad relationship he treated really bad but he changed after i kicked him out of the house
