Hi,
I can understand why you would think a man with a jealous streak, would have major issues with this kind of work.
An interest of mine has no issue with this line of work, understands that it is work but that I also enjoy it... yet in a social situation, when approached by men, they will get the arse visibly. I think that is because firstly it is under their nose and secondly because the guy is not hitting on my work persona (though that is still me, no act) and the 'real' me.
Long term relationships and marriages can work whilst doing this work, if both parties act like adults. If you have been on/off a lot recently then I think you should be extra cautious in jumping in again too fast as it is different with this work IMO. Living with someone whilst doing this, they need to understand that your phone will ring and you will have to check emails. Whilst at times you will switch your phone off as you need some private time, that also occasionally it needs to be on when in the middle of eating etc as Client X can only call then etc.
