Sorry but I need to rant I haven't done that at all on here.... My son " father" really makes me angry he's been on child support since 2012 and hasn't paid a dime but can afford to get animals and shit then he wanted to call me last night and let me know he's planning on proposing to his girlfriend... like where did you get money for a ring ugh..... My husband has done more for my son in the past year and a half then his "dad" has in 5 years
