Mom Prefers the Ex

I will never understand how a mother can prefer someone who didn’t make their kid happy over someone who does

My current boyfriend emotionally and mentally supports me. My ex never did. My ex offered to pay for a flight to California while we were long distance. We had only been dating for three months. My mom thought this was acceptable. I didn’t, for multiple reasons. I didn’t want to feel like I owed my ex for anything. And I explicitly told my ex I was willing to donate plasma and set aside a little bit of my $300 biweekly check to pay for the flight myself. He kept pushing the matter

I’m just so frustrated about this because she’s always saying she wants better for me. I’m happy with my current boyfriend, even if he can’t offer to pay for trips to California or anything

It’s starting to drive a wedge between my relationship with her because she can’t just mind her own freaking business
