Try and add him back. I have added 2 of my ex boyfriends on Facebook and they added me back. So all I can say is just try it and see how it goes. Oh and I wouldn't just send my number to him, because that would be creepy.

Oh lord.. I signed up on this site just to be able to comment here..
i don't want to be harsh.. but that may be what you need...
HE deleted you, he does not want to be friends with you on facebook, and more than likely does not want your number. if you add him, and he's the one who deleted you; he will either feel bad for you and accept or just ignore you. regardless of who broke up with who.. he's the one who deleted you on facebook. do not add him. do not give him your number. move on, forget him. :/

really you already know what to do.
'We are no longer Facebook friends but I stalk him... often sadly' --> there your own words, if you think its sad that you stalk him, why are you still doing it? I can understand the wanting to look, I've done it before. But in the end, i he doesn't want to be friends with you its the end of it. and anyway, surely not stalking him and not having him on facebook will help you to move on from him?

I agree with the last two comments. If you haven't spoken since February, it is quite apparent that he is living quite well without you. You really need to move on. If you're too proud to re-engage him, then its quite apparent that you don't really want to be with him, because if you did, you would swallow that pride of yours.

And if I'm wrong, and you do care about him, be mature and message him. Say something along the lines of "Hey, sorry for the way I've been acting as of late. What have you been up to since February?"

If you cannot do that, then you need to move on.

I agree with the previous 3 comments. It's pretty clear what you should do. And that is move on. I know that sounds harsh, but he's deleted you and you guys haven't talked since February. It seems he doesn't want you in his life. I understand looking at his page (we've all done it on occasion, I'm sure), but don't make yourself into the "crazy ex". Just let him go and move on. I know it's easier said than done, but staying where you're at isn't healthy either.
You can shoot him a message and ask how things have been, but I'd say that's about as far as you can go without entering dangerous waters. So, my advice is just to let go, altogether.

I also joined this site just to comment on this. I honestly don't think that you should do either. Don't add him or message you. I know it's hard, but I don't think that he wants to keep into contact with you. Let him move on his own terms and if he ever wants to contact you, I'm sure he will find a way

dont u ever add him or even talk to him .. he shud appologize . im sure hes the one who hurt u .. n he shud pay for this .. karma will get him dw .. he jst doesnt deserve him .. !!! u deserve someone better who wud die jst to add u on his facebook !!

Yeah, just add him back or message him and ask him how he is. Don't throw a phone number at him! Creepy!
