Honestly this doesn’t seem like a healthy friendship. You said you two had a falling out but were you going to attempt to fix things? If you are I’d have a serious talk with him about how you are feeling and set clear boundaries with him. Let him know that you have to worry about your family and feel like right now this is not being understood. Let him know it’s okay if he needs to spend time with his family and you want the same respect.
If you’re not wanting to repair things or it doesn’t work out, that’s okay too. Sometimes friends come into your life and you have great memories with them, but then things are meant to end for whatever reason. It doesn’t mean that all of the great things that happened don’t mean anything anymore. It’s okay to let those memories make you smile while also looking to the future
It’s also okay to grieve the friendship. It becomes easier over time. Maybe you can write a letter that you don’t send that you use to get out any last thoughts and feel a little better. What you do with the letter after is up to you.
You can do this!
