I went out with a guy who was my friend for over 10 years so we dated now for 18 months as he was mixed up about feelings his ex who he was seeing for 3 years while she was living with someone else,so we just took it slowly,he didn't come home at all one night so I packed my bags and left and I haven't heard from him since now I have heard she left her guy 4 months ago and is living in the next street! I still haven't spoken or seen him and my mind is going round round thinking that they are now together.

Did you try calling him before you packed your bags and left?

Hopefully you'll have some more information by now.

I did I rang him up to 5am with no answer then he walked in at 6am where he had been in a party but couldn't remember who with or not to sure where it was just a vague answer but I was leaving he said I love you!

Wait what?

One night he doesent come home and before you even spoke to him - you packed your bags and left?

No... I had packed my bags at 3am... he rung at 9pm saying he was on his way home and he didn't come home until 6am I waited for him... then waited for there reason which was he can't remember so I left

Why are you worried about it.. you walked out on him. You ended it, so move on and let it go.

You left without giving him the option to tell you.. or sober up for that fact.

You made your bed.. deal with it.

Why did you leave him because he came home late one night? It happens...

And of you left him you can't expect him to be waiting for you so he went with someone who actually wanted to be with him. Also, if you choose yo leave why then are you wondering so much if he is with her? It is their business, not yours. You handled a situation very immaturely and are now noticing that you made a mistake... If I was him I wouldn't want to be with you either. Adults and humans understand each other through communication, if you don't allow time for that then you have no right to complain afterwards.

Good luck,

Sounds like he was not really over the ex, which means you didn't really have him any way. If you left him as quickly as you did there was not that much on your end either.
I think you know what's up which is probably why you left so fast. He is most likely back with his ex.
Move on.
