Backstory is he was/is married for 12 years, no kids (had fertility issues), says they're separating through no fault of each other (just that they grew apart according to him). He was on a dating app and so is she apparently. He has gone to separation counselling etc. with her to sort out finances, etc. (they separated ~9 months ago) and he says they are on friendly terms (she still does him favours e.g. running errands but there's no emotional bond there).
Says he's waiting for the "no blame" legislation to come in (no idea when that will be ..??) before officially filing.
Been on a few dates with him, all great so far - lots of talking, some physical contact (making out etc) but obviously, I feel awkward about the fact he's still legally married.
Any advice? How long does a fairly simple divorce case usually take (i.e. fairly amicable, no kids, no fighting over finances)?
