I felt this with my ex-T too. I think it went both ways though, she was the exact same age as my mother and single with no kids.

In fact, just before she turned cold and abandoned me for 6 weeks and told me we couldn't be close anymore she said "I would never abandon you because your mother abandoned you and you need me."

Typing that hurts my heart.

The new one is very kind and warm but she's only maybe 8-9 yrs older than me. Seems safer.
