Is it normal for my ex to...

Sounds like he wants you back. You need to set boundries

Tracy...

Yes it's normal for him to get territorial but it's not a good thing and you shouldn't allow him to keep you on a leash

Sweetie this boy is still in love with you,but he does not wanna admit it therefore he thinks it's ok to be creeping on you and feels jealous and defensive over you. The best thing you can do is not answer his calls that will tell him he needs to get a life and find someone else.
Hope this helps!
<3

normal but not right. he obviously isnt over you, and although it can be quite fine for exes to remain friends what he is doing is just torturing himself. make some space between you, and although he may not like it just know you are doing him a favor. I feel bad for the rebound though...

some of them u do...

Well if it didn't end badly such as you just grew out of love but remained friends I see nothing wrong with that. You don't have to hate your ex's.

You should keep a distance from him.

Sounds like you extended the "friend" card and he's goonna cash in on it to inflicked damage. He needs to be more smooth to inflicked revenge lol.

No you need to stop contact with him. It's not normal to remain close with an ex. Matter if fact it's a very bad idea to remain friends with an ex. Just sets you up for cheating and/or heartache.
