What to do when my boyfriend is tearing my family apart?

After being divorced with two children for the past 5 years, and dating numerous, numerous, people, I think I have finally found the one that I want to be wtih for the rest of my life. Although he can be controlling and jealous, I love the relationship that we have. He doesnt drink and party (like most my ex’s and friends do) and I admire him for that. We get up early in the mornings and have coffee at the picnic table. We enjoy going out dancing on occassion. Back in December he asked my daughter permission to marry me. She said yes. I asked my children if they approved of him living with us and they both said yes. Once he moved in and started being a part of the raising of the children, my daughter (15 years old), now decides she doesnt like him. She said he changed me and I am more strict. That is true only because I am not out partying and drinking all the time. None of my friends like him either for the same reasons ~ even my best friend wont come over to the house anymore. My daughter is now living with her dad (and gets to stay out all night if she wants because he doesnt care) and she says she wont move back unless I make my fiance move out. Half the time I think that I should just kick him out so I can have my daughter and my friends back, but the other half of me says forget what they all think and I need to make myself happy. I forgot to mention that my son who is 10 has a great relationship with this man (better than with his own father). My fiance built him a treehouse and now helps coach his football team. I am so confused ~~~ Any suggestions ? (P.S. my daughter and I are currently going through counseling to see if we can all eventually have a workable family relationship)..
