I guess now I just keep moving forward, work, gym, etc and be a good father for my kid when he is here. Reaching out to my ex is not an option no more especially after the birthday text and email which I got no reply. I guess enough is enough. No woman in this world should be worth of so much trouble and humiliation.
I have talked to friends, family, etc I will let my ex pick up my son or have her daughter come to my place for night overs if my ex reached out which she most likely will. I'll just be 'invisible' in the background, quiet and let her do as she pleases. Only reply to her msgs short and straight to the point about the kids. If the kids interactions will make her come closer to me, great, if not, so be it.
