So called "tough love" is not happening

My style of parenting and my boyfriend's is very different. We haven't lived together for long and our kids are in very different age groups. I have a son 16 and a daughter 14. He has twin girls who are 6 and a third daughter who is 3. My kids live with us full time and do not have fathers who are involved. His kids are only here every other Sunday during the day. They are working towards overnights every other weekend and are hoping to start that this summer.I have a very relaxed, somewhat "friend"ish relationship with my kids. I was still in high school myself when they were born and they have never had fathers at all. It has been just the 3 of us for a very long time and we have been through a lot together. We are not structured, really, and don't have hard and fast rules and my kids get a lot of freedom. We spend a lot of time together, have similar taste in music and clothes (well, my daughter. anyway lol) and talk openly about everything. I don't censor music or movies. I don't care if they drop the occasional swear word. My kids do well in school, my son is a varsity football and baseball player, my daughter is very involved in the drama program. We are doing just fine the way things are.My boyfriend seemed to adjust to living with us fine at first but lately he keeps trying to create rules, to implement more, structure to change things. Last night we had a bit of a meltdown. My son got home a half an hr later than he said he would be (which isn't something I consider a big deal) and my boyfriend flipped. He said a LOT of harsh things I do not agree with, my son got angry and started yelling...it was bad. Once my son was in his room my boyfriend started spilling all kind of stuff I didn't know he was feeling and tried to convince me it is time to tighten the reins on my kids and that they need "tough love". I do not believe in tough love and I have no issue with my kids or how we have always done things. As long as they watch their language and keep their music/tv/movies whatever clean as long as his kids are around (which they do) how I choose to parent them is not his problem. He can have all the structure and rules he wants for his own kids and I will stay out of it. But he needs to do the same.Im really surprised that my style of parenting has upset him this much. Neither he nor I want any more children and he is free to parent his kids however he sees fit and I will stay out of it. But he needs to do the same.Sorry this is a lot longer than I meant it to be. via /r/Parenting http://bit.ly/2IHNLHp
