Is it normal that i constantly worry that my boyfriend will leave me

Don't worry about it all the time. I have learned with age worrying about what someone is going to do will not stop them from doing it. You cannot make someone do or not do something. I can tell you one thing of he does leave you yes it will hurt but I PROMISE you will get over it and then find someone better.

Yes, it's very normal. Your constant worry about your boyfriend leaving you comes from your insecurity. And sometimes when you care about him so much, like you can't live without him, you would have the constant worry too. To help yourself relax, you should reassure yourself that he's with you right now and the fact is - he loves you.

You should be more confident about your relationship with your boyfriend. And you should understand that it's love which ties you and your boyfriend together, so as long as you love him and he loves you, you two should be happily together! :)

I do this alot and we love each other a lot I'm just so scared so I ask him all the time

Chill out. If he leaves it will be his loss! You need to make him feel privileged to have you - then he won't leave. Don't ever be too available or predictable and always make sure you have fun together instead of fighting.
