Ayngl, I don't know enough about your sitch, but based on your time lines in your sig... it's hard to say whether dating is something to consider at this time...

How long were you together with your H, considering you are at 2 years M at this time...

My personal opinion is that dating while M is not an option... but there are others who have been S for so long, pending D, that dating is just a given... and in other cases, with short Rs, dating after being apart for one year might be reasonable...

In the end, it's a choice you have to make, but I will offer one observation...

By your words, you sound depressed and you sound angry...

Neither of those two things will contribute to the development of any type of meaningful R...

So, having said that, if you choose to go out on a date and some... FWB stuff... well, that's your choice...

IF you have any thoughts about R with your H and trying to save the M... how would dating and more affect your chances of R? How would you feel about "breaking" vows? How do you think your H might feel?

In regards to the M, it could be a moral dilemma...

There's also always the risk of STDs...

And then there's also the risk of emotional damage, to you, to your H, and to the OP you may date...

So really, it doesn't sound like your ready, but in the end... no one can really advise you...

I know that doesn't help and you know the above... but that's the best "advice" I can give...
