What to do?

Been with the father of my children for five years we have a four and a 2 1/2-year-old. Our relationship started sucking when my little one was about four months old he has always been a hands off dad he tries to make me feel guilty because he’s the one providing now since I lost my job in 2017. We are not legally married and he basically owns everything the car i drive the house etc. me leaving the job to dedicate raising the children full-time is nothing to him so I said I will hire a babysitter now and start looking for a job because I feel so unappreciated used and taken advantage of. he’s making his money and not putting anything aside for the children he told me that he has made his estate planning and has put his brother to manage my portion of it… I have no relationship with the brother whatsoever he’s never been in the girls life maybe seen them a few times. I live in limbo every day he has a bad day he tells me to go find an apartment and move out so I’m supposed to move the girls again for him while he spreads in a 6400 square-foot home... I don’t know what to do I spoke to a lawyer and she says that the process of custody could take up to two years and it’s going to be very grueling being that he is not agreeable and will not fight fair I try to talk sense into him telling him to do anything that makes him happy (we haven’t slept together in 2 1/2 years) he keeps telling me that I aggravate him and I said you should then move out and make yourself happy.. he just leaves the room and nothing gets resolved even his business partner told him that he can afford to move out of this house and buy another one but for some reason he just wants to control me because he said I will support you until you find a boyfriend… I need to keep it together for the girls who now are starting to understand when we’re not talking to one another and they keep saying that they want mommy and daddy together ..it breaks my heart But I cannot make him love me he doesn’t say I love you anymore and I have stop saying it all together we started couples therapy he joined the first two sessions then didn’t show up anymore I don’t know what to think or how to proceed I’m thinking perhaps it’s better to wait a little longer until the girls are a little older because he cannot take care of them right now But at the same time he tries to sway them against me and that is very disturbing because he is the nice cop and I have to be the bad Cobb when it comes to eating healthy teaching them structure etc.
