The only reason I would advocate sending a final email is because I'd hate to think that some jerk was out there, imagining me as Miss Havisham, endlessly waiting for him. I can accept that that's probably just me though .
A wise friend told me that "You see only what you want to see" when it comes to an online relationship
of any sort.
But sending the email, even if it's "so long", lets the guy know that you had been pining for him and you'd given him enough headtime to make one final contact.
In a nutshell, I think your friend got played. It's sad and unfortunate. I recommend a carton of ice cream and a marathon of some sort, then move on. Don't send anything, don't initiate contact. Alter his contact information so you still have it, but it identifies him as a dork and doesn't interrupt you.
Guys like that tend to rotate through their marks.
Why do I know this?
Many moons ago I met a guy online. We were friendly at first, but after a long time of basically being acquaintances, we started chatting more and became attracted to each other. We met in person and really hit it off. Unfortunately after 10 days we had to go back to our respective corners. We continued with video chats, text chats, etc. We were making plans for him to come visit me, etc.
In the end he got kinda dodgy and then initiated a fight between us. Then he went all "WOE IS ME. I CAN'T TAKE THIS FIGHTING" and dumped me right then. I was devastated because we were just kinda bickering and the reaction was so over the top compared to the argument. He still wanted to talk though and let me know he was having "heart problems" due to the stress of the argument. He immediately moved on to his next girl.
About 8 months later he came nosing back around me. My other friend in his town and he had become roommates. I guess things had waned with the other chick or the one after her, because he started sending me messages. Being of the mind that sometimes its best to keep your enemies closer, I allowed him to chat. I kept it superficial and I didn't take anything said seriously. I rebuffed any requests for video or voice chat. He was quite entertaining whenever he'd chat while drunk - You find out great stuff. In the end, he picked another fight. [Although... He told me he was going to do something while we chatted that skeeved me out and I mentioned it to my friend. Due to a limited resource, Ex wasn't supposed to do that. Friend confronted him, and next thing I know I'm hearing that I'm untrustworthy and a horrible person. Like I knew.] He wasn't getting what he wanted out of our reestablished contact, so he needed a good excuse to cut contact. I feel as if he expected me to jump right back in with him or he was waiting for the frost to melt. When it didn't...
After some long discussions with my friend regarding ex and his habits, we came to the conclusion that ex is addicted to the "honeymoon phase" of a relationship
as well as being a bit of a commitment-phobe. He has no problems making plans way into the future, but once the walking on sunshine starts to wan and the relationship
needs maintenance, he moves on to the next victim. In my case, his next just happened to be the one that was before me. Stupid girl had been pining for him for months and waiting. I have this feeling that as soon as I had gone to bed after he dumped me he was on the phone calling her since he kept me strung along for almost a week.
Jane's guy will probably try to contact her at some point. It depends on how long it takes for him to rotate through marks. Her best plan is to not respond to anything he sends (not even how pathetic it sounds) and to move on. I'm glad I did. Ex's plans to improve his life never did materialize, instead staying at a supermarket job, eating chocolate and chips, and interacting with women on a webcam.
