So I've been pissed off that my BD. hasn't called to check on his son who is 3 or to see how I'm doing with carrying his 2nd, however I shut his phone off because if you're moving your ex/BM in can't she buy you a phone?

... Now he's still in contact with mutual friends through an old Obama phone but hasn't made an attempt to reach out, should I cut his phone off or be like FU he (our son) don't need you. Am I hurting my son by being spiteful? 😔
