Most Helpful Guy
Be gentle with his feelings, show empathy, agree to meet up with him like tomorrow or the next day.
And ask yourself this... Do you. Or Do you not still consider the idea that you could get back together? If you decide the answer is most definatly no, then still meet up with him stay friendly, but tell him honestly and openly that it really is over. He needs a gentle response, but he needs finality.
And bare in mind it's an extremely sweet gesture for him to be reaching out to you, and though it may seem creepy, you know him, very well, and if he wasn't a creep during the relationship, he's not a creep now. He's just not over you, and wants you back and the fact that he's coming back after 8 months is THE SIGN OF A COMITTED MAN. and you DO want that, they're rare.
So think about it seriously and don't ask your friends about it. if YOU want him back, hurry up ad take him back. if you DON'T, then when you started the relaitonship you sorta took on the responsibility to respectfully end it WITH FINALITY and closure, in the event that it ever ended. you can't dodge the pain of letting him down, you have to go through it, it's gotta happen. Then you can stop feeling bugged, and you can both move on with your separate lives. and believe me, that in itself is a different kind of happy ever after.
