Is he over it and I'm reading too into things?

So I dated my ex for a year and a half. We met online, were both 26 and the first sincere "I love you's" to each other. Things were awesome. I got into a great program 1,000 miles away and took the chance, inviting him to come. He said he needed to stay with his family and friends. We both cried, agreed to end things, and had more awesome times the last month I was with him. He came to send me off to my new home and then returned to his.

A few weeks later he was back in full pursuit. We became long distance with both of us visiting each other twice from July to January. After the last visit when we road tripped back to my place and had more of a happy friend time than a lustful lover time...things got distant. He had been unemployed for about 3 months (and still is by choice today) and I was pushing for him to commit more (as in move to be with me since he didn't have a job where he was at.)

For Valentine's Day I asked if he would come visit me since I had to work and had already purchased plane tickets to see him a month later. He said he would think of it but never let me know until I brought it up to him a week before Valentine's Day. He sent me some flowers he ordered from flowers.com. We facetimed and it was lackluster but he swore he was still into the relationship as I sensed something was up and gave him an open door to take if he wanted it. A few days later I spied him on an internet dating sight for the second time and called it off, then asked for a compromise with him telling me he had to think about it, then called it off again. We cried and agreed to end things.

Several days later some girl the exact opposite of me is his facebook friend and 3 weeks later they're in a relationship with him publicly declaring it and posting pics (which he never did with me). I contacted him 3 spread out times since the relationship ended through fb messages. After the 3rd time, although he immediately responded to all 3, he left me hanging when I responded to his responses and I decided I needed to let him and this girl be. He's now contacted me the past two times, including today for my bday but again keeps me hanging when I ask him a question. He says he's been "wrapped up in shit and distracted but really wants to be friends." I told him I missed him often and wasn't as moved on as he was. I asked if he was ok but he didn't respond.

I feel so replaced. Have I been emotional with him to the point of no return? Is he in love again so fast?

Well, honestly, there's not much future in a long term relationship unless one of you will be able to move in the long run. LTRs are difficult to maintain. Thus, I don't see the point in them. He is probably not "in love" but is dating and in a relationship with this girl. You can be in a relationship while you build love, but you don't have to be in love to be in a relationship. Plus, there's no telling how long they dated before they made it public on facebook. He likes you as a person and doesn't want to lose you as a friend, but he's allowed himself to move on since there's not much chance of yall being together because of the distance.
