Found shortly after our second child was born that my husband has been on Tinder for over a year

I’ve caught him in so many lies since finding out. He told me he would never meet up with anyone and could never do that to me, but after more digging I found the phone number of one of the women he was meeting up with. He claims she was the only one and she confirmed when I spoke to her that they didn’t do anything physical but they went on 2 dates. Dates that he planned with her the day of our daughter’s birth. Dates that I stayed home and watched our babies for, thinking he was out with friends. He’s treated me horribly since I found out too. I could go on and on about the plethora of things I’ve found on his phone and the numerous lies I’ve caught him in since I found out but I don’t want to make this post too long. I’m truly broken. We have a 2 year old and 3 month old. We’re going to therapy and I don’t believe in divorce and as fucking stupid as it may be I’m hopelessly in love with him… has anyone been through something similar? I just don’t see how we can ever have a normal relationship again after this, especially with the constant web of lies and gaslighting he’s been streaming to try and conceal the full extent of his infidelity. I just can’t see the light at the end of the tunnel right now and I’d really love to hear from someone who’s been through something similar and got through it and what their experience was like.
