In a nutshell, I was dumped by someone that I was absolutely crazy about end of last year. His reasons were fair, I was recently separated, still spending lots of time with exDH (we get on well).
The guy who dumped me and I had known each other for years and I had been aware that he fancied me for a long time, and when I separated from my DH he was kind and supportive. Within about 2 months kissed me and we began spending more and more time together. Things escalated and it was a whirlwind romance - all good.
He became increasingly frustrated that I was still spending lots of time with Ex-DH (nice guy, DC together etc). And the guy that dumped me became increasingly withdrawn. Told me that he wants to wait longer until I’m ‘more’ available but was clear that he saw us as a long-term option. I absolutely accepted this, I’m not keen on drama and I’m not going to beg someone to want me. So that was it, over!
Occasional chatting texts, sometimes texts about how he feels about me, saying he loves me etc. Not initiating any meet-ups etc, so along the lines of what a shame, bad timing for etc.
Roll to yesterday. He sent me the most awful text as I had visited friends in the town where he lives for a few days and had a great time. I didn’t contact him as we’re not together etc. He’s said that he’s angry, disappointed etc that I did see him or tell him that I was in town?? 
Was IBU not to call him and more than that, am I right in thinking that this doesn’t indicate that he still wants me (but rather that he’s not as nice as I thought he was)?
Any opinions greatly received, I have no idea about dating!
