Known this person for over a decade and we've been on/off casual fwb during that time. Over the past year I've become more attached, well I thought we both were (not in a romantic relationship way), they have been local and usually they move around so we had spent a lot of what I thought was quality time together. 

Now they've moved and we've been texting. I saw them off when they left and everything. I was supposed to visit from out-of-state on Sunday and they've ghosted me, blocked my number, hung up on me when I called from a different number. All the plans for the visit were set - but now looking back they were very hot/cold with me.

I've been going over the texts a million times and I'm feeling like I've been too clingy. I would never imagine them to do this to me, though. If it were about another person they were seeing they could just tell me because that's the nature of our relationship. I just don't understand and I'm heartbroken and alone. Now I feel like I see the signs they were trying to shake me off or make me noy want to see them. Seeking consolation -

TL;DR: ghosted &amp; blocked by fb who moved out of state and I had plans to visit in 3 days.
