Is this the end of my marriage?

[P17]

And my H told the OW that he has filed for D a few months ago. Nope. I would have been served and I called the courthouse to check.

I think that is called hedging his bets.

I don't understand how the OP deals with a married person who is also a liar.

We could make a list

1. Sex.
2. Companionship.
3. Sees an easy 'ride'.
4. Sex.
5. Get's life given to him on a plate.
6. Desperation.
7. Love (it's there).
8. Sex.
9. Low self-esteem and low self-worth.
10. They are a loser and can't get anything better.
11. Etc.

These are mainly from my W's situation but I'm sure there are a lot of common ones for others.
