So my boyfriend is travelling and spending 3 days a week at his ex girlfriend's house at the moment so that he can see his son. Whilst I have absolutely no issue with this at all, it bothers me greatly that he then spends time with his ex "catching up" and "hanging out". I can't see him at the moment because of the Coronavirus and I'm starting to get resentful that they have games that they play together and jokes which he then tells me about days later. Am I being a psycho or is my nerves/jealousy/anxiety justified in these circumstances?
