Short version married for 19 years. Two kids one 18 other 10. I work for my husband and over our marriage he has strayed a few times always citing sex . I have taken him back but things quickly end up back to his old ways. Last year we split up for a few months and he came back cap in hand saying he wanted to be different and promised all sorts. Fast forward three months and he’s been confiding in at first a woman who works for us and more recently being overly flirty to the point he has asked on messages (which I’ve seen as I looked due to suspicions) to come to her house. As yet she hasn’t that I’m aware of said yes but last week she did something in work that he would have sacked other people over and it was brushed under the carpet. I know he wants something from her but she’s not giving in. The result of this is he is frustrated and wanting sex 4 or 5 times and he has woken me up in the middle of the night looking for it. It’s driving me mad and when I say no or try to put him off he huffs. Our sex life was always 2 times a week ish and more on holidays but this is intolerable
