End of year celebration with my children and their families

Hi this year we are going to rent a cabin at Backbone State Park to celebrate the end of the year of 2017. I am really looking forward to it. The date we have set up is Nov. 25, and 26. I regret that my oldest son Matthew will not be able to come. He has special needs, has been found by the state back when he was sixteen of being a sex offender. I know he has had a problem with feeling rejected by his adopted father. Yes, my three older children were adopted by their step-dad. I let him adopted them since I did not feel it was right for him to be supporting them without any financial help from their birth dad. Their birth dad chose not to come see them just because while they were small I  wanted his visit to be supervise since I felt I could not trust him to bring them back and I was also afraid for both my two older daughters safety with him, I say this because my oldest daughter when she knew her dad would becoming home she acted like she was scared of him. and one time after putting her to bed I rub my hand on her head and a whole bunch of hair came out, I told her dad then that I was going to keep an eye on it. She was only 4 years old at the time.  Their own birth dad abandon them after I divorce him. This is the reason, I finally gave up after eight years of marriage was because I could know longer take being cheated on or being both verbally and physically abused. If my two older daughters do not like what I am saying, I am truly sorry. But what I am saying is true and I have to share it. I  did not want to divorce their dad, I came from a broken home too and I really wanted it to last. But all the love that I gave him was not reaching his heart. I sincerely hope he treats his wife now like a princess. Life sure is not fair. I hope that Matthew's sisters will go see him especially his two older ones. He does love them so much. I hate the fact that it backfired when all I wanted to do was protect Matthew from my second husband that constantly treated Matthew like an escape-goat. Here is a picture of my son Matthew
