A little while ago I met up with an old friend (OF). We have known each other for decades, got on really well, there's always been a bit of attraction there but we've never really been single at the same time. This time we both are, we ended up telling each other we fancied each other, and going back to his place for (mind blowingly good) sex.
The thing is, I escaped a violent and abusive marriage a year and a bit ago, I have two young DCs and very little free time. I am also acutely aware that I have made appalling choices of men in the past, and that I have a responsibility to my DCs and myself as their DM not to introduce any more crap men to our lives. So at the point of initial snog I told OF that I am not in a place to have a relationship, I have very little free time so I can basically do occasional dates and sex but that's the lot. OF was ok with this, but he hasn't treated me like a fuck buddy - he took me away for a lovely weekend, talks to me about books we both like, suggests future holidays.
The thing is, I've started to like him a lot, and maybe even fall for him. I'm pretty sure he's a positive thing for me and has potential to be for my DCs - I'm not great at spotting red flags but none have arisen so far. He's single and childless so no difficult blending issues. The way things are at the moment is lovely, but the thought of him feeling free to see anyone else is intensely painful. Should I try to revisit the discussion and say that I do now want a relationship? If so, how the hell do you bring that up? My DSis says I am overthinking, should relax and enjoy it and let things progress. OF is not in any way a player and has had a crush on me for about 24 years, so he's likely to hang in there now. But I worry I've set the basis wrong and am creating a mess which it will be harder to sort out later. Any advice please, Mumsnetters?
