Doubting myself

So me and hubby are splitting up after 5 years 1 child and one on the way which he said he didn't want and I have a gut feeling he is cheating on me. I called it off and all my emotions are finally hitting me I feel like it's the wrong choice and I'm starting to think well what's really wrong with our relationship apart from that he is lazy he spends all his time and money on himself and motorbikes he said he feels like he's in a prison and wants freedom.(all that and I'm still contemplating staying) he isn't even showing any emotion seems like he is happy and he doesn't care that I'm leaving with our child. It's hurts I still do love him and I really hope that our time apart we can fix this but he keeps saying he doesn't think anything will change. And that we have tried and nothing has changed, but part of me is angry and says stuff him I will be fine on my own I will provide for our children cause obviously he won't and doesn't want to 😒 ahh emotional wreck here
