Single fatherhood 2

So my son went to his mom's for the weekend. That's hard on me not to see him for so long. Seems like all I do is just sit and wait for him to come home lol. She is a good mom but she dose have a habit of not telling me thing's about his weekend. Like one time she didn't tell me she moved to a new town and she didn't understand why I was upset about that. I didn't know where he was if he boyfriend went with her to her new place what kind of people he was around. If you think I went over board let me know but she did try to let her sex afender bf by around my son and not tell me he was a sex afender and a drug dealer around him man this last year and a half was a full one lol
