Listen to the teen first, possible talk to both parties. If the abuse continues both should separate.
Not at all. However you should always be safe and be comfortable with the relationship.
The best age to handle any kind of relationship is the teen years. 13 is the first year that this should be started. Any younger than that the child can have a hard time understanding the relationship.
You should go up to him and see if he feels the same way as you feel about him, I wouldn't attempt to force him into anything and don't feel downed when he doesn't like you back. You should however if he is of the same sexual interest should get to know him a little more, have a little closer relationship (friend-wise first) and then let it kick from there!
No matter what the sex is, if someone is pressuring your teen into a relationship, you have to stand in. Your child's (teens hate to be called children, or any variation of it by the way)safety should be your number one priority. You should have a serious conversation with them and let them know that you won't judge them if they choose to accept, but that they should only accept if it is what THEY want.
If a teen is in an unhealthy relationship, they need to get out as soon as possible.
There is not really a NORMAL time period for a teen relationship to last. It just depends on the people in it and how compatible they are with each other.
Yes I regulary talk with my teen about their relationship questions. It is important to be consistant, honest and open. You want your child to be comfortable talking with you.
I have never been in an abusive relationship but you should get rid of whoever is hurting you, and if he continues, tell someone about it.
Almost always.

If you are talking about meeting for the purpose of a relationship, then no pre-teen of any orientation should be dating like this. It is entirely inappropriate and in many places illegal.
