Just to be clear: Are we talking actual salivation here?
There’s no doubt that double standards exist. And all of them bring their own issues, so if you’re going to pick one to make waves about, make sure it’s one that’s actually making waves in your relationship.
Yes, indeed, anyone drooling over someone who’s not their mate can be downright disrespectful. So if your girlfriend is doing something that is hurtful to you, by all means, talk about it.
Don’t be afraid to admit that it bothers you as an individual. Trying to cover up your feelings by turning it into a gender war only means you’re not being true to yourself.
But if you’re not bothered by it and are just trying to make a point, you might regret choosing this particular battle – especially when she brings up the many other double standards that go in the opposite direction.
So, from an argument standpoint, you should bring it up at your own peril.
You can’t change your husband’s choices. What you can affect is your own behavior – and what kind of mom you choose to be. Will it be one who gets help to get healthy and do what’s best by them, or one who is mired in hurt and anger (however justifiable those feelings are)?
Seek a therapist with experience in these issues; you need to feel heard, and to develop strategies for coping with your feelings. It’s not about flipping a switch to get over it, but to have a space that’s solely your own where you can gradually process your emotions and move forward. You’ve been through a lot. You – and your children – deserve for you to feel better.
