This is a slightly funny one to phrase so I hope I write this correctly.
My on again/off again partner and I have a funny background. In the past I have often found him to be distant and not a great partner. We broke up a few months ago (I ended it) because I wasn't happy but we have kept talking, he is trying his best and I can see that. We have met for dinners, coffees etc but nothing physical has happened while we figure it out.
However, I have taken the 'next step' and invited him over to my house next week. This to me is a clear sign to any adult that I am interested in moving to the next step and he seems to have backed off. To me it was a big step and I thought about it a lot first. He said he'd like to but I haven't heard much from him since (we were previously speaking everyday). This is a bit weird, no?
