To ask what to do?

[WishItWasSunday]

I don't post often, and usually wouldn't post in AIBU, but I'm a bit shaky and don't have anyone around right now to ask advice from.

So I have a DS who is 17, very mature for his age, and who I trust a lot. I work shifts as a nurse, so he often fends for himself with a close neighbour if there's any issues. He sometimes has friends over to stay, which he always runs by me beforehand, and I'm almost always ok with as by and large they tidy up after themselves.

So I got home about an hour ago from work. I finished early as I have been working extra time and was owed a few hours, and I was wreaked.
I got in and saw that there were beer cans on the side, and there was a smell of pot.
I was a bit grumpy, but decided that was a talk for the morning. DS's bedroom is upstairs and mine is downstairs, each has its own bathroom. I went for a shower, and got dried, came out of my bathroom wearing a short dressing gown thing, and almost screamed because X, a long time friend of DS was in my room. He was definitely drunk, and he sort of lunged at me. He caught my sleeve and my hair. He was easy to push away, and quite disoriented, and he stumbled out of the room when I put my "mom' voice on but I'm left very scared. My dressing gown doesn't really go below my bum, and he'd pulled the top open a bit. I'm embarrassed and furious and upset and I honestly don't know what to do.
Any advice?

Hi Op, I’m sorry things have worked out as they have with your XP/ P. He really has shown you who he is. You didn’t deserve that reaction from him, it wasn’t of your making. You deserved support, cuddles, understanding and kindness. Don’t settle for less x

Oh i hope you are just a little less sad today. Be proud of yourself for finding the strength to stand up for yourself a second time. Your ex wasn't someone worth keeping around.

I'm pleased that you made progress with your son though. That's really good.

The thing Iv found is where partners are concerned it's not until your going through a hard time or are in a situation where they should be supportive or understanding that you see the truth of their character and find out if they are someone who's worth building a life with.
That's doesn't mean you shouldn't try to meet someone new eventually.

He has shown you who he is and I'm sorry it was now when something really awful has happened (which means you could have done with his support!) but I'm glad you listened.

If your struggling, just hold on to the fact that as awful as this is you will get through it and if nothing else it has brought you and your sons relationship closer.

OP - how horrible for you.
You seem to be doing the right thing with your DS though. It is very hard for them at 17 and easy for them to screw up without really intending to.
You and he have talked and that's good. The rest, at the moment, is not so important.
Take care
