My boyfriend told my friends that he's got another girlfriend besides me and that he loves her the most. What can I do and how to deal with this kind of situation?

Find a new boyfriend.

Okay I'll try to get over him ey! By the way thanks. :'-( :( :-(

May I ask how old you both are?

Do you want a boyfriend who thinks it is okay to have two girlfriends? If so, then you accept it and share. If not, then dump him.

Don't try to replace him just because you think you need a boyfriend or all of your friends are in relationships.

Don't jump into a relationship just because it is the thing to do. Being single is okay.

You dump him. You don't deal with a situation like that. You remove yourself from it.

Hum, first what is wrong with having two girlfriends or two boyfriends, or 4 boyfriends and so on.

A serious mistake too many make is getting too committed to one partner too quickly. Dating is just suppose to be that, you date several people and over several months may narrow down to one or two and then over time commit to one.
