Cherry LanePeter,
I hate for you to feel like you have not being doing the right thing by your daughter. Number one ....There is no right or wrong in parenting. The ONLY skills one has is what they know from themselves being raised and what each partner can add or subtract from the parenting role. I personally think you are a wonderful parent to be concerned about your daughters social life and to want her happiness in a relationship. This is all you can do after they reach a certain age. SUPPORT SUPPORT SUPPORT! Even if it is not what YOU would choose for her. I am in the process of trying to get my daughter OUT of a relationship with a man that is a control freak. We point out the negatives and let her know the door to our home is always open. Unfortunately there are no easy answers for parenting and there certainly are none when they are adults. I just find myself having a lot of faith in her to leave him and I pray for her day and night. Even though I have STRONG negative feelings about this doof......I have to use restraint and remain positive and up beat around her. The decision MUST be hers. I bite my tongue and give it to God at night. This is all we can do. I wish you and your Daughter well and relish the moment that for now you are the ONLY man in her life and soon you will lose that position. The walk down the aisle to give them away is the longest walk of your life and your heart breaks with every step. I cried all the way!
Good Luck and God Bless
Cherry Lane
