usually not because once you come back you still haven't worked through the problems. however a short break may allow tempers to drop, rationatity to prevail, and allow each person to gather their thoughts and feelings so that they can come back and discuss and fix the problems that caused the need for the break.
talk to him.
when he stop hanging around you
Have her back in case she has a problem.
let him and act like you don't mind
Wait, so you want someone to break up with their boyfriend for you? ok...umm...there has to be a reason to break up first i guess. I agree with the person above me. If the girl wants to break up with her boyfriend, she will. She's not going to do it just because you don't want them to go out.
Then take one yourself too.
It means that people are spreading rumours or are trying to break you up!
Well if I were you I would break up with him but since you don't want to break up with him I guess when the baby comes just become its stepmom.
If you want to break up with him, be the bigger person. Try to do it although difficult. If you do not want to break up, keep it going, and then on.
Ask him whether it is true!
There are no proper signs of a girl whether she is going to break up or not. But certainly there are various things that tell that. It might be the case that she flirts a lot.
Tell him you will call him in a month if you are still single.
