I'm going to chime in here. I may have a different opinion than most. I believe it is never a good idea to critise another's parenting skills. Never.

All we have to do is put the shoe on the other foot and it will become clear.

Dealing with blending families etc. is often difficult. In fact the stats are worse for divorce in blended families than in first families. I have always read, heard advice by counsellors that the person on the outside should only be a friend to the children, not a parent. It is up to the natural parent to do the parenting.

I have quite a few single friends and I remember one of them dating a guy and telling us how he let his kids get away with things etc. he couldn't parent, she had to step in etc. Well that relationship did not work out at all.

Also, young men often do not mature until after age 25, this was told to me by a doctor. Doesn't mean that can't help out, have a job etc. but this kid lost out on important years in his Dad's life and wants to make up for lost time. I would side with my kid too if I were in his situation. You really shouldn't even think this way in my opinion, it's him or me. This is a no win situation for you.

I dont' remember reading how long he has been living with his Dad. If it is just a short period of time, ease up on him and let him enjoy the relationship. I think the fact that his Dad wants to spend time with him is wonderful. In my opinion that makes him a good Dad. Once he has got used to the area he will make friends and then he'll be out with them giving you more time to spend with your BF.

I'd say some patiences is in order here. Six months is too early to be thinking about marriage and judging this father/son relationship.

Just my two cents.
