Relationship problems

My hormones are all over the place. Me and my husband have been together 6 years married only for 10 months. We have 2 boys together 5 and 1 month. I'll admit our relationship has always been rocky. After having our new baby I seen a change in him. He says baby don't look like him he's to white which isn't true my baby is light light brown just like both of us I'm sure he came out white because he was brand new but he picked up color. He demanded a dna test! I did get upset what you don't trust me were married ? yes I'm very hurt that my baby has to go thru this. But we did it and waiting for the result still. Yesterday we both were having some drinks while our kids were asleep he got drunk and started saying I've been treating him like shit I put our kids before our relationship and they won't be there for me when they grow older etc that he will be there for me so why do I put them first then he goes on to say I'm putting him in the direction of talking to another women again 2 years ago he made a tinder and was messaging a girl he was tired and gave the girl his number by mistake and she texted while we were in the car and he freaked out I took her number down and she sent me all the screenshots 🤣 I was hurt he bought me flowers candy and a bear the next day smh promise to never do that again. But he says thus last night ? I'm going thru postpartum as well it's super bad and I decided to have a lady come to our home for help and now going to start consuling with him. But last night everything he said I couldn't do it and locked him out while he was smoking a cigarette. He tells me I'm not a good wife and mom coming from a man who doesn't help with the baby while I cried at night because my son wouldn't stop crying he was waking up every hour it takes him half an hour to finish the bottle he had the nerve to say it's such an easy job. Idk if I should try therapy or just leave.
