Honestly, that sounds awful. Now I have a question, he is trying or do you think he will actually be of a father figure to the child? Because if so, he really shouldn’t be out when you need someone, especially with other girls, if not, while having to respect his decision, he’s still horrible for just leaving you like that, he doesn’t seem like a good person, especially if he’s not answering your questions, it’s your right to know if he is with other girls. Do you know when he’s coming back? Maybe you could let him know that you’re not ok with that then.
For the meanwhile, do you have anyone else to support you? Any family or friends who you could talk to about this? I’m sure they’d be able to help you out.
Let me know if you need any advice, or just want to talk,
