I've just started a new relationship and the chap I'm seeing works shifts, nights, weekends, etc (they work in the NHS). I don't for a second think he's seeing someone else or that there's any duplicity going on, but it means that we only get to see each other about once a week. There have been a few weeks where it was twice, and I've stayed over at his at weekends.
However, this means that it seems to be difficult to get the "momentum" where typically when I've started going out with someone, it's been once a week, twice, three times and building up, and this isn't happening. So, it feels that we're seeing each other, rather than making that leap to DP.
It's been about two or three months now, so there's no panic, but I wondered whether anyone else has faced this problem.
