confused about this

in 2006, I met this guy, I was living with Jamie(which is my current b/f) we all went out to a concert thingy. and this guy(Shaun) seemed to like me. well a week or 3 later. in 2006. he came and took me to the zoo. well he wanted a kiss, but I didn’t know what to do because I loved Jamie but me and Jamie weren’t dating at the time. but any way since then. I have talked to him randomly through out the 3 years. over the computer. once I seen him on his motorcycle. im like are you kidding me. well he seems to like me. I think I talked to him last in feb or march. he said something along the lines., I am still available if you want me. I said ok. well then I messaged him again. he is on a dating website .. that I had for a while. and boom there he is..that is where we talk. well I think in may. his profile said he found somone. so I wrote and say congratz. hes like nah. I put that so maybe people will leave me alone… I only tell people this if I like them.. so im like OK another hint… then I wrote again. and he just deleted my message im like OK confused.. but for 3 years. HE ALWAYS pops up somewhere. I could have not thought about him for 3 months and boom he is randomly right there. I think about him every day. even though I only hung out with him 2 times… I want to write him and tell him something, but I feel like I am a crazed weirdo lol. I dunno. I am in a relationship with Jamie. father of my son. we have been though a lot and he has cheated A LOT. and maybe for 9 months he has been good hasn’t done anything. but I don’t feel how I did for him like 9 months ago. I guess that last chick really did it in. I love him. but I am not head over heels for him anymore… but what the heck do I do about Shaun and me thinking about him alll the dangg time. I mean I am up all night just thinking about him. and why he wont go away. id feel weird writing this to him.. anyone help? I feel stupid! just be nice to me lol. I just dont know why I cant stop thinking about him

should I just like edit this as I am writing it to him and just send it. not like anything can bad happen, besides him deleting it. or saying I am stupid and crazy lol
