I’ve cut all ties and claimed maintenance. After a lot of heartache I am now settled with someone new, dc is 3. Having spent all pregnancy and maternity wondering and hoping ex would see dc, I’m now so worried he will re emerge and disrupt what we have. I obviously wouldn’t stop him seeing dc but I’d be anxious. He’s in his forties if that makes a difference - still single and obsessed with his career apparently so I’m hoping he’s still very much focused on that.
