Can't trust my man
I have a problem trusting my man because whenever he has to do something for his child, I cannot call him any at all. If I do, it gets him upset.
If I have to take my daughter to see her father for maintenance, he calls me every so often. I have had instances of unfaithfulness from him, but he said it was a mistake and he made some changes.
Pastor, how can I trust him again?
I think what you are trying to say is that you are not free to call this man unless he is expecting a call from you, and that is because his child's mother might be visiting him.
You have a child by another man and he has a child by another woman. Evidently, you don't trust him and he doesn't trust you. A good relationship is built on trust, respect and communication. all three go together.
If you believe that you belong together, then seek some help and learn to live with each other.
