Overthinking things?

I'm feeling a bit annoyed with myself. Please bear with me, having been on my own for the last 3 and a half years, I'm struggling to understand whether I'm misreading or overthinking things.

I'm a single mum to my two teen lads, I care for and home school my youngest who has learning difficulties, and work 2 days a week. I'm reasonably happy on my own, sometimes I think it would be nice to be in a relationship, but for the majority of the time I don't want to be if that makes any sense? I'm happy in my in company, although I do like the company of others.

I received a message from a guy I dated over 7 years ago (just the one date), he's a nice guy and he lives nearby and said he'd spotted me out and about and thought he'd ping me a message to see how I am. We chatted over text during the evening and I mentioned I go out for walks around our estate a lot which is probably why he's seen me a fair bit especially now the warmer months are here.

He asked if he might join me on one of my walks, I said he was welcome to, he said when he was free and we arranged a day to catch up for a stroll.

We met up this evening, and went for a nice long walk, we chatted, he more than I, but it was nice to catch up and felt relaxed, a bit like catching up with an old mate. Dating and relationships came up in our conversation, I said how long I'd been single, that I've not dated at all, and how I enjoy my own company and space, but I also enjoy the company of others, but I don't feel the need for a relationship. He mentioned that he feels put off dating women because he hasn't had much luck with relationships in the last 3 years.

As our walk came to an end, he said how much he'd enjoyed it, and I said that I had enjoyed it too. He started to say 'I would be nice to..', and I kind of spoke at the same time/finished the sentence saying 'it would be nice to do it again sometime'. To which he replied, 'yes, how about a cup of tea outside on my patio next time, I've got three different coloured tea pots to choose from'. I laughed and said that sounded nice, then asked him what days he's usually free, he said it varies due to work so it would be easier to ping him a text when I'm free and we can sort something out.

We then parted, he went to take my hand, but I held my arms out and said, 'give us hug' and hugged him.. he hugged me back quite tightly (I'm a hugs kinda gal). I headed home and he pinged a message a bit later to say, 'thank you, really enjoyed that' (the walk), and I replied, 'Me too, it was lovely to see you'.

I'm sat here now feeling confused and unsure of how I came across having jumped in with the 'it'll be nice to do it again sometime' and the hug? I felt I rushed right in with it. It would be nice to catch up again I did enjoy his company, but that's all, I enjoyed the company, so I can't work out why I'm getting so worked up about how I came across?

Sorry I appreciate it probably all sounds really silly, but I just needed to write it somewhere. Thanks for reading (listening) x
