Is it wrong to want the man I'm in a relationship with to prioritize me?

Wow, unfortunately you have put yourself in a situation that only will end in grief for you.
Any 55 year old man who would lie and take total advantage of your youth is mentally unstable. Unless your only in this for the money? Run like hell and save yourself years of grief!

Run for the hills. Because he will do exactly the same to you.

Don't expect a man who cheated on his wife and stepped out on his family to prioritize you.

This man won’t prioritize you ever. You’ll always doubt him and should because he’s out for himself.

lose him
today
keep walking
don't look back

you're being used

and if he ever left his wife for you - congrats! you'd have a cheating husband that you can't trust alone

Well... Lets try to put this delicately.
You were a side chick. He got caught and decided WTH might as well stay with the side chick now.
He prioritizes his wife and kids because that is what he wants. He wants to be back with them. He is just waiting for it to blow over with them and he is going back and you will be left out.
Use it for what it is not for what you want it to be.

Yes. You aren't his priority. His family is.

You should not be with a married man!

Yes - kick him out of your life. He is a liar and you will always be second best whatever he says. You CAN, and WILL do better.

He left because she found out and kicked him out, it's likely he would never have left. You can do so much better.

Not wrong in the least. But you won't be his priority.
He only left her because she found out. The whole relationship started on a lie. He was married with kids and never even told you. He's a loser.

Surely you can do better than that.

Oh boy, this whole thing..... how to say it, it doesn't make you look nice at all. I mean he's a total ass who deserves to get his marriage ruined for what he chose to do, but why would you decide to keep on with someone like that? At your age you could do so much better, the age difference might not seem like an issue at this point but it will be obvious quite soon. I'm sorry to tell you this but I think the man just wanted a young girl to sleep with.

Leave him cheaters cheat he is using you until another turns his head

You were his "bit on the side", he never intended for you to be the main event, and he won't ever look at you in that way.

Have some dignity, leave him, never look back, he was and still is using you

Its wrong to stay with a man like that. Not only is he a cheater and betrayer but also doesn't love you. Can't you do better than that or just need a sugardadda

Take his money and leave

That's funny if you believe that

Not wrong, at all!
