I am ok now. I was able to pass off the running away as simply having had too much to drink and wanting to be in my own bed. We had been messaging on and off whilst I was away which was nice. It wasn't full on but it was enough to know that we were still thinking of each other. I saw him the day after I got back. We went to dinner and I ended up staying at his. We stayed up most of the night talking. Nothing in particular, music, art, books.
It was a working day next day so I brought my laptop just in case and he set me up in his room whilst he worked in the living room. We were both busy with work, but it was very 'comfortable' - cups of tea, and kisses on the top of the head when we walked past each other. He even gave me his keys so I could pop out and get coffee (he doesn't drink coffee).
We made vague plans about meeting up again when I get back from my holiday with the children (I go today for a week). Again, cautiously optimistic.
H came around on my last day of holiday and discovered I had changed the locks and was NOT happy about it. I got a string of angry messages about "joint property", "legally obliged" blah blah blah. I wrote him a very well worded email saying I would not be giving him a new set of keys, that his insistence on coming and going is "unreasonable, unnecessary and unnerving" and he could "apply to the Courts if he wished to take it further". He is going to take it up with my solicitor. Not sure what him taking it up with my solicitor will achieve (she works for me) but oh well.
Anyway, Croatia was amazing, things are going well(ish) with the new man and H is p*ssed at me. All good my side then.
