My boyfriend has been telling so many other girls he loves them, by email, text, phone and messenger. I don't know what to do. He says nothing has happened, but I can't trust him anymore. Is this relationship worth it? We've been together for 2 and a half years and I'm fed up with it all now.

Trust is key in any relationship. If you feel that you can't trust him, then maybe it is time to look at your relationship and decide what is best for each of you.

That being said, do you know these girls that he says I love you too? Are they friends or just random women that you have never met? If they are friends, then maybe he does love them, but is not romantically interested in them. There are different kinds of love.

Some of them are random women but some are exes, people from his college, his next door neighbour etc, I've asked him not to do it before about 3 times, but he still does it.

He needs to respect you and your wants and needs. It sounds like you need to sit down with him and really communicate what you are feeling. Hear him out, but also let him know how you feel. He might not understand how upset this makes you.

Yea I might do that thanks.

You need some space from him just so you can see things as they are and can make a decision. Trust is earned not given, so has he earned your trust?

This guy who you call a boyfriend has no respect for you.
He is insensentive and selfish.

Communiate this issue with him and make sure you make yourself clear, if he gets all up tight about him let, just make sure your message was clear.
