Christmas Fun

I was divorced and had 2 children who were with my ex-wife and in the next state, she lives close to her divorced father. I'd no close relatives living near me, except if you count an ex-mothers-in-law. My wife mother and her didn't get on very well and as I get the children every second holiday. It was her best chance to see her grandchildren, her and me got on fairly well before the divorce. But kept in touch after for before mentioned reason, my ex is a very spiteful woman. Had it in for her mother since she divorced her father and made him look bad. Anyway, last Christmas we were alone to together, not my turn for the children. One thing led to another, and relationship went sexual, we could've left it at the once. But didn't we become very regular lovers and still are. Neither in any other relationship and prefer the simple relationship we've, sex whenever we want no hassles type. But changes happen, nothing major her rental was sold, and she couldn't move in it with as that would cause problems her daughter who would withhold the children as result. But I'm quite well off even after alimony and child support, I bought the house right next door to my place. Now my ex-mother-in-law lives there rent free and sleeps every night with me. It wasn't an expensive place to buy run down 2-bedroom cottage. She stayed with me while it was renovated to suit her and improve it. Her stuff is in the cottage, but she is in my bed every night, my ex-wife doesn't like it that her mother right next door to me now. But she can't use it to stop the children visiting me either. She mentioned once, but I had my lawyer send a letter saying I've a right to see the children and her problems with her mother aren't my problem and said if she withheld the children, I would go for full custody. Her father is her lawyer and he saw it as unwinnable for her to provoke me. Especially when she tried stuff before she lost. I've my children and they have their grandmother, nothing my ex can really do. Sex between me and my ex-mother-in-law is on hold during the children's visit. But we will make up for it after they return home and we're together most of the time anyway.
