Well I am rather friendly with my ex husband as well as with his wife. Heck my ex husband and his wife sent me and my husband generous wedding gift when we got married. Saying that most certainly we don't love each other. We love our spouses.

I see no issue with this man giving his ex 1k. They have kids together and she is pregnant with his child. I don't see how him sending money is wrong. I also see no issue with this man talking to his ex. They have 3 kids.

I see an issue with him openly stating he doesn't love a woman he sleeps with , but loves his ex ( that's frankly a very offensive and rude statement to make to a woman he has sex with, and I wonder if it's deliberately intended to offend )
