Have recently started speaking to someone new, who has told me he has 2 children with two different women. He maintains a good relationship with his first child and sees them often, however, he has no contact with his other child and hasn't seen them in almost a year. He states this is because his ex has not allowed contact and has called her every name under the sun. This has put me off a bit and I have distanced myself. Surely a mother wouldn't stop a man seeing his child for no reason and there must be some explanation for this? Would this be a red flag for you?
