Help. Should I tell him I miss him?

I’m really struggling to get over my ex.

He broke up with me two weeks ago. But I love him and it hurts so much. I don’t know what to do.

He’s been my best friend for years and I’ve always felt this intense connection to him.

But only last year in October we got together. Because we both finally confessed our feelings for each other one night when high....

Anyway, fast forward to the future:

I don’t know what to do now?

I’m living with a mutual friend and so my ex is still always coming over...

But last Saturday at a party he started talking to this girl he knows. And basically spent the entire night with her right in front of me.

And then after he came back to mine (as he doesn’t live in the same city)

On the drive back to mine it was just me and him and I was drunk and went crazy on him and said some things I shouldn’t have said out of jealousy I guess.

And now, I know he’s gone on a first date with that girl. Tonight!

He called my housemate asking if he can spend the night here tonight.

My housemate said yes without asking me.

In a way I was glad, cos it means he wouldn’t spend it at hers...

And he’s here. I’m with him in the living room watching and movie. Just me and him as our friend went to bed.

NOW:

I want to tell him I miss him. I want to try again. Love him. And if he feels the same way then we should try again. If not, I love him enough to let go, but will need some distance for a while.

SHOULD I SAY THAT TO HIM OR NO?
