Do you have an ex that hugely regretted not making more effort in their relationship with you after you ended it?
2 of my 3 LTR exes have felt this way. I loved them and was committed to them, but they took me for granted and just didn't give enough either emotionally or (in the case of ex husband) carry their share of the domestic / childcare weight.
Both of them were regretful for a very long time. The most recent one still comments on it.
I really think 2 things. If you'd wanted it to work, knowing that I was telling you what I needed, WHY didn't you change? And also, mate, it's your own fault! Own it.
Is this just a man thing or do women do this too?
