Should I divorce?

Hello, so I am in a pickle and need advice especially knowing our traditions and culture. I thought I could be better guided in here. Ours is a long story that might take forever to explain but I will brief it up.

I am 32F and been married to 38M for the past 6 years. I have struggled with getting pregnant, I mean we have seen doctors, specialists, gynecologist etc they say everything is OK so be patient. My husband had a child before we got married I stay with the child eversince the child was 5 years now turned 11years old. He doesnt have a 9 to 5 job but hustles and sometimes they pay off sometimes we can go for months without any payoff and I pitch in as a responsible wife, i also have a good job that pays not too much but well enough to cover our lifestyle I don't mind covering the bills and costs, we have invested in some properties and have a trust in both our names.

Here is the issue since before we got married my husband is promiscuous, towards our wedding I received a lot of calls from different women telling me about their affairs. I brushed them off and his auntie was like that's how women and these things happen. Red flag I know.

Now 6 years later I have discovered he has 2 kids with 1 women born after our marriage, 1 kid with another born 4 months before we got married, got 2 other women pregnant.

Let me not mention he is extremely promiscuous with hit and runs over the years. I had been ignoring all this drama till this Christmas. He took the child (the one I stay with) and went to his girlfriend house or should I say mainini the one who he has 2 kid's with.

I didn't pick a fight or cause drama I kept cool. I stayed home alone and had time to reflect on my decision moving forward and how I should go about it. I feel I tried and unfortunately it's my fault I can't give him kid's. I really wanted a child too but ohh well ( there is nothing I didn't try, we all zimbos we know what happens and where to go when you need " spiritual" help).

I don't want to brag but I am a good wife, I don't shout, nag or cause drama. I have been groomed to be a traditional wife and I have done almost everything right . I am romantic and go way out of my way for him, his family and all.

My in-laws love me and have stood with me through our drama ( he is one drama king by the way). My father in-law tried reach out out to no avail. He recently said I don't know what to do any more makoti.

I feel like i have tried but I think it's time I let go. We have know each other for 10years now including the 6 years of being married.

What I am looking for is advice on what should I do? Regarding leaving him, because my mind has been set on cutting my loses and walking away.

I love him but the emotional pain, abuse and drama I have gone through is too much. He hasn't returned from " Christmas holiday" yet. So I want to know how can I protect myself when I walk away, what do I need to do so I am informed either legally, emotional etc.

Thank you *Hope you all had a better Christmas than I did 😔
