Hello Gray, and a warm welcome to the forums.
It is sad that this happens but there are times when all we want to do is move away for whatever the reason is, and you should not feel any remorse for wanting to start a new life, but to be blocked by your 'friend ' is not the best resolution in helping each other.
Being away for a year the people we once knew as being friends move on in life, form different relationships, get another job which maybe somewhere else, so contact with them slowly disappears, circumstances make this change, and know that all my 'friends ' I once had I'm no longer in contact with even though I would dearly love to hear from them.
It's understandable your current boyfriend doesn't like you mentioning your previous friends name, just like I didn't want my ex when we married to talk about her previous boyfriend's names, simply because they are only memories and the same applies if I did the same.
Can I suggest you seek some assistance by seeing a doctor who can then refer you onto a psychologist using the mental health plan, which entitles you to 10 Medicare paid sessions.
Thanks for posting your comment and would love to pear b0ack from you.
