Some background. Was casually seeing a guy last year for three months. Who was hot and cold and it was on his terms. He moved back to his country and then we spoke quite often throughout the year.
He then decided to move back here and was commenting on all my Instagram stories etc.
He asked if he could stay with me if he couldn't stay at a friend's for a couple of days. I said ok if he had nowhere else to go (I only have my bedroom in a shared flat)
He didn't need to in the end.

We went bowling, in which he was 45 mins late and we missed our bowling time. I was a little bit annoyed but it got sorted and we had fun. He then asked to come out for my birthday the week after.
Then after that I felt him pulling away and taking longer to reply. I let him have space . I then text after 10 days and he seemed happy to hear from me
He apologised for being quiet but said he isn't ready for a relationship and was slowing the vibe down but isn't running away from me and should meet this week.

It got to Friday and I asked if we were still meeting he said he was busy and we should.meet next week.
I left it and have not contacted.
After a week he text he was watching a parade and thought about me. I replied and asked how he was and he didn't reply. Two days after he commented on my insta story.
Now it's been two weeks and nothing. I don't know whether to reach out. I wasn't pushing for a relationship but maybe just came off too strong after being excited he was back.
Should I reach out?
