Well , I don't agree with some replies here...Maybe I'm not right but I would like to tell You story of my brother and his girlfriend.
They've met when he was about 17 and she was 15,about year after they started to live together.Just like that.They were going everywhere together,to the parties,pubs ,to visit familly,just everywhere.When he wanted to meet his friends she has to go with him,and so has he.She was quite jelous everytime he has talking with his female friends.That's why he started to talk with them keeping it in secret.I knew about it but I also knew that it was nothing.He just didn't want to argue with his girl.About 1,5 year ago he went abroad to work and she stayed in our town.I visited her almoust everyday(we are quite friends ),but someday I saw that she treats one man more like a friend.She was talking with him everytime we were in the club or something like that.Sometimes they've met in the cafe .Then few months later she decided to move to my brother,because she didn't want to be here without him.When she was already with him ,she confessed that she has an affair with this guy .My brother was quite depressed about it.At this moment they decided to say everything what they are doing,who are they meeting etc.I saw he was quite depressed,one time he even cried on my shoulder.She told me then that she shouldn't ever treat him like she did,that she was so jealous and didn't trust him.She was so jealous that she even started to belive that he is cheating on her.I think that's why she started that affair with this guy.Things were getting worst ,till one day she just found out that she is pregnant(surely with my Brother
).This not already born child made everything much much better.So now they are really happy together,and we all are waiting for this little boy
He'll come in july ,so just few months left.
The point on this story is that sometimes it's worth to give another chance.Blow the tears,bite one's lips and wait untill it all calms down.Some people need some time to fix their thoughts.So in my opinion just don't give up,show her that You are there,standing by her side not only when it's good but also when it's bad.Of course if You really love her.
