If you have not tried it yet, try to have a conversation about it. In most cases it's best to talk to them one on one. Let them know you have a serious concern and what to talk. Think about what they do that bothers you and what they could do (and what you are/ are not willing to do) to improve the situation.

A friend is someone that takes you serious when you tell them you feel like a punching bag. They are willing to look at their own behaviour, apologize where needed and it matters to them that you feel that way.

So two things can happen:

1. The result is a good and honest talk, after which the situation changes (immediately). Then the friendship will have evolved into a better one.
2. the result is not a good talk (they don't take you serious, or laugh at you or tell you to not be a softy, erc). Then the friendship was really not a friendship at all.

Option 3) is ghosting but then you don't give them a change of outcome 1.

Option 4) is to do nothing. Your resentment will likely grow over time (the fact that you ask the question makes it very likely that you are getting fed up). So the friendship most likely won't last.

So talking can be scary and a risk. But (assuming you stayed friends all this time because of the good things) it has the larges change for this to take a positive turn. The friendships you loose over it are the ones you are better of without, the ones that evolve are worth keeping.
