I want out this relationship

My boyfriend decided he was going to do a DNA TEST on our 2 years old and 5 month old. He thought he was being slick and waited until he thought I was sleep to do it. I saw him swab both of them. When I confronted him he lied about it Tried to say he didn’t do it. But the wrappers from the swab kits were in the trashcan. So I duh them out the trash and sat them on the kitchen counter…. He had nothing to say. Here’s the thing we talked about him establishing paternity I had no issues doing that but in court , I wasn’t against the DNA test so why try to be sneaky ? On top of that he went around telling his family about it. I asked him why he felt the need to tell his family our business no response. He even started sending screenshots to his mom and dad. My family thinks he’s being coach by his mom. Why 2 babies later are you doing this ? He told his family he had doubts because I took my oldest son on a play date with a guy friend😑. Who’s fucking Gay…. I am eembarrassed for my children and myself you basically just told your family what you think of me and honestly I don’t like being talked about where I can’t defend myself. I never cheated or given him a reason to act this way. He has though and it’s his own guilt ! He didn’t come to the birth of our second baby because he said he was upset that I was pregnant! Like I got myself pregnant…. On top of that I have no home support or from him all he wants is sex . And shows every lil Interest in the kids He even refers to them as his brothers…. As a mother it’s very hard to watch I don’t have love for him anymore how could I love someone who mistreats the two most important people on my life my sons! Sooo he I asked him how long it would take for the DNA results to come back he said three days a month had went by and I brought it up he told me they emailed him the results . I said cool email them to me so I have a copy he said No! He said they didn’t have names on it duhhh dumb asss when you do at home DNA test it’s just the number of ppl tested and the Percentage of relation for Privacy and identity reasons🤦🏽‍♀️ I even showed him that’s what it says on google he still wouldn’t give me the results. All this guys cares about is himself . It’s hard being 5 months postpartum and not having a melt down . I want to put him out so bad but my family keeps telling me to think about the kids I am I don’t want them growing up in a toxic environment…
