Advice needed.

I dont know what to do but recently found out that my husband has been keeping a secret daughter from me for years. Rewind, we met in the beginning of 2020, kept contact and remained friends or whatever, in 2023 we decided to proceed with our relationship, we had a child and got married last year. I’ve asked him before if he had any other kids out here jokingly last year, and he was like “you know females have tried to pin kids on me but I’ve took a dna test and wasn’t mine” and even showed me this little girl who is now 6 years old. Well now it’s caught up to him, he got a call from a family member saying he had a child support letter come into the mail, he called me and explained to me what happened and that he knows the child isn’t his(lies). He has been lying to the baby mom saying he doesn’t live out here anymore and that he’s “homeless with no job or phone so how can he pay child support” which I told her the truth we just got a whole house together. I get in contact with her and she tells me everything, how this man has been calling the little girl, how he met up with the mom last year and took her out to eat while I was pregnant. She said he has not seen the girl in years maybe since she was around 3 years old. She had no idea he had a wife and another child, my daughter is 5Months and I just found out I’m pregnant AGAIN. He has told me we should start trying for another child the ending of the year which obviously isn’t going to happen cause too late for that. He says the child isn’t his because he took a home dna test and it came back negative and he left since…. It’s just so many lies after lies. The little girl has his whole face and looks like our daughter twin literally. He works of of town and is gone for a little over a month so we haven’t even talked about this cause he’s been exhausted and I just feel betrayed and lied to because marriage would have never happened if I knew he was keeping such a huge secret. He says he feel like I dont want to be with him anymore because I wont tell him I love him back but I dont know, I loved him and I wanted a family and build a family with him and he’s lied to me for so long, how can I believe you even love me after you’ve done this to me , we haven’t even been married that long for me to file for divorce. I just dont know what to do, I haven’t slept in two days, ate in two days, my life feels like it’s in shambles. I just need advice on how to move forward I feel like I lost everything, He told me to quit my job 4 months ago and stay home and raise to babies, I dont have any family to run to, he was all I had and now I dont even know what to do or how to work something like this out, I’m betrayed, lost, hurt, I feel like he took my heart out of my chest and stepped on it and put it right back in. Someone please talk to me and help me, I dont know what to do.
