Sorry for the long post.
Meet last December and we immediately clicked, spending lots of time together and keeping in touch multiple time per day. We had a great holiday in January and decided to book another one for Easter. Things were going well but we had a couple of discussions triggered by me because I was feeling insecure (not saying it was all my fault, but admittedly discussion triggers were silly) After the second one, he said he has already been in a relationship where discussions were happening on a daily basis and didn't want to repeat that. Towards mid-March he starts becoming more and more distant, fewer messages, cancelled appointment etc. I ask him if everything is all right and he says works is stressful. We spend a weekend together with kids and he makes no mention of planning for the week after (he always spends Mondays and Tuesdays at mine as my son is with his dad). Because of this and other stressors in my life, we have another discussion and I decided to ask him not to talk for a couple of days to get some headspace. Beginning of the end: I get in touch and ask to talk, he refuses and says he's too busy at work,then we have another discussion because he is incredibly argumentative on things like he is always coming at mine ( he never complained about it in fact, he is much closer to his workplace from where I live and I even gave him keys to let himself in) . , when we manage to talk again he sayshe is confused and wants to think about things. He then left me after a couple of days, straight after I told himI want to try to find a way to work things out. I don't contact him anymore and he gets in touch after a few days saying he misses me. We stay in touch (he was away for work) and then start meeting again but he is very distant and cautious. In the meanwhile, the Easter holiday is fast approaching, and he says he is not sure whether he wants to go. I tell him he needs to decide in time for us to cancel without losing too much money. Notice that I have my son half of the time while has his every other weekend, so Easter is probably 1 of the few weeks I can go away. He keeps taking time, because "he is too busy" "he is too tired to think" etc. I get increasingly frustrated to be kept in a limbo and other behaviours he displays like not displayingany affection, simply ignoring my requests of having some notice before organising things together, etc. So I decide to cancel my part of the holiday booking and let him know. After that, we had just a couple of brief conversations about the refunds and then total radio silence. So we kind of mutually ghosted each other :-( I am gutted things have gone this way, on the other hand, I am not sure whether there would be anything I can really do to fix our relationship as things have started going wrong after he is gone distant. Shall I just let it be and move on?
