Its tough but move on. You do NOT want to wreck a relationship. Trust me.
Unless this is a long distance relationship, you should definitely be talking more often.
Write and call him once in a while. Distance should not separate love.
You should snog your boyfriend if you are a little deep in your relationship.
'Ex' means the relationship is over and your boyfriend should move on from his ex and his attention should be on you. Good communication skills are a must in any relationship so it would be wise for you to discuss with this problem with your boyfriend and tell him to choose between you and his ex. Don't buy 'the friendship' excuse. Moving on from an ex is always healthier.
If your crush has a boyfriend then you are not her crush. There is no relationship, you are just a friend.
If he changed yes but if you think he is the same no.
Unless he was moving to deliberately get away from you, then no. He may have a genuine reason for moving. If he is a bit further away, it will make it more difficult to conduct a relationship, but if you are interested in each other, then it will not be a problem.
IF YOU HAD A GOOD RELATIONSHIP BEFORE.
Involve your parents.
when you want him to
No
He should evaluate how much he really likes her, and if he thinks that he can handle a long distance relationship with a girl with a new guy (and can foot the phone bill) go for it.
