Is it normal for a mother to check when my ex boyfriends online?

tell her to get her own ex boyfriend

This may be hard to hear but... your mom is a whore.

My condolences.

Don't you see?! She forced you two apart because she wanted him for herself! She checks up on him because of her desires. She probably fantasies about him too. There's probably no need for you to ask why it is that she does this. I doubt that she'll tell you.

Your mom sounds obsessed.

She's a sleazeball who wants him for herself. How disgusting!

She probs wants him in her pants or she is bored and has nothin better to do

This is very strange behavior. Tell her to stop. Spying is not cool.

She's tryin to keep it in the family. old women need lovin too.

It sounds like she broke you up and keeps checking that you r not still going out behind her back

She should just talk to you and be direct not go behind your back. if she does care she should face you about it. tell you why she doesnt approve.

truth is parents today do that. they rather not face their kids directly and let them do what they want but they snoop later on.

Shameless

You let someone else, break up your relationship... Why?
