I love him with all my heart n so does my daughter but he been needy a lot lately n I don’t understand y at all like I am open with him I tell him we’re I go n if I not at work he is mostly with me... we be laying in bed n he will put his arm around me but also put his hands where I don’t want him to as well like I don’t like tht when he does it I move his hands n he pouts like a little two year old n throw a fit... this been going on for awhile but we have our good days n bad days as well any relationship... my daughter sperm donor raped me I found out tht I was 3 months pregnant 3 days before my sweet 16 birthday...
