Advice from the old lady:
Listen
@lonelylibra89 you know your behavior is abominable. And welcome to the forum.
In order to offer salient advice I have a few questions:
1. Are the children yours and how old are they?
2. Why did you get married in the first place?
3. Do you want to salvage the marriage, or the relationship with your children, or both?
4. Are you prepared to do what is required to rebuild the trust?
Please share on each of those points. Your culture would be useful to know as well. American and Western European culture is different than Asian or Muslim culture, for example & how you handle things best will be influenced culturally.
My initial read is that you had kids first and got married later, perhaps out of obligation, which is less than ideal, but of course I could be off base. Or perhaps you are from a more patriarchal culture but she has taken the babies and gone home to her parents. Those details matter in how best to help you, as do your goals for the relationship.
If your wife is the mother of your children you are best advised to have at least civil discourse with her. Lying obviously is not conducive to that goal.
Many of the guys here have done the marriage and kids thing, many have been divorced, some are currently married, etc. I myself had 3 kids with my first husband, divorced after years together, kept an amicable relationship with the children’s father but have since remarried. My youngest is still in high school and lives with my second husband and I. So there are people here who have been in all the various permutations of relationships here.
Please share a bit more detail so we may better assist.
