NWR at all but..wondering if any1 else dealt with this or feels this way about an"ex"

i have been with my FIance for 3 years now. For about 2 years before that I had a weird relationship with a guy. I really thought he was so in love and just didnt realize it (he was dating other girls and i was in love w him, but dating other ppl), we never really got that serious.

Anyway- oddly enough he texted me on teh day i got engaged to see how "life was going"  I told him I got engaged. He said "when are u getting married, do i have a chance to steal u away before then". which is annoying cuz It took me a LONG time to get over him, and he never wanted to date me.


Since then he contacts me about once every other month asking how I am....

Weirdly i had a dream about him last night. Then he showed up on my facebook feed this am at the top!! (he doenst have fb but was teh best man in a wedding with a guy im not really friends with but am"facebook" friends with).
Then today he texted me "was at a wedding tis weekend and thought of you. i cant believe the mistake i made to never date you. i just was young and didint want a  gf, its the biggest mistake i ever made in my life. i think about you every single day"

This is all very flattering ya, but he dicked me around for so long (excuse my language) and I've moved on and im finally happy.

I just want to contact him back and ssay" i appreciate you finally realizing that, but please do not contact me again"
One of my friends said just to ignore him and not to open the flood gates.
My mom said "tell him to scram"

He literally shows up in my life all the time, and i'm kind of sick of it. It makes me remember how bad i felt to be a stupid girl chasing after some guy that doesnt love me. Part of me then starts to think about the things that could have been (like what i had wished for 5 years ago!)- even though I love my fiance whole heartedly and thats unfair to him and would never want to be with someone else. I think a girls mind just does that stuff.

Should I contact him and tell him to scram? Or just ignore him? I do care about him as a friend (we have mutual friends but NEVER run into one another, esp now that i moved cities, and i will likely never see him again in my life- unless its the holidays)....but i just hate that he makes me feel like this everytime he contacts me.
