I would offer to go for councelling and if they refused and said they didnt want to know me any more I would back off.

I have been on the recieving end of somone not getting that I didnt want to know and it is scary and hard work it made me hate them in the end when we could of been friends which is silly way for adults to behave. Especialy when children are involved.

So I would ask them if there is somthing you was doing wrong and if you made an effort to stop doing that particular thing would it alter how they felt ? If they said yes then suggest councelling you never know it may work....

If not then back off.
