Is that an acceptable compromise?

Not sure if this really belongs here but I am sure that all the wise ladies here will be able to guide me.
In short, in the last few years my social life has just disappeared. A few things on the top of each other, incl 2 dcs. I have decided to do something about it and start going out a bit more often. Nothing wild, just trying to go out and meet people.

I am thinking I could go one evening a week out to do some yoga (fab teacher!) and one night out in the month with a group I know.
I am sure it doesn't look awful but... I am also working 2 evenings a week (Back home between 7.30 and 9.00pm) and DH wants to go out one evening a week (Back at about midnight. Has always done so) and have one full day every other weekend for his hobby (again a normal state of affair).
If I go with my plans, we won't be seeing each other a lot and I remember only too well the time when he was travelling 2~3 days a week AND was still having some time for himself (same as above). I remember how resentful I was that he was in effect away 7 days out of 14 and I am weary to do the same now....

I am working so can't fit these activities during the day and (most of the) people that I see/meet are working too so only evenings are possible.

What do you think? Is that an OK arrangement?

To me it sounds fine. You're equally entitled to enjoy a social life, yet even with your new plans you're still going to be socialising less frequently than your DH currently does. Are you worried that he's going to have a problem with it, or are you just concerned that you'll seem hypocritical if you made a big deal of him having free time when you didn't have any hobbies previously? Making time for your own hobbies and social life will likely make you feel less resentful of him having free time of his own. As for seeing less of your DH, can you commit to making the time you do have together count? eg. go out on a proper date night together once a month?

In a typical month you'll have 4 evenings and one night out to yourself.

During that same period your dh will have 4 nights out and 2 full days to himself.

Why do you think that it's your free time that should be sacrificed so that you have more time together, even though he will have more free time than you will?
