You have gotten a lot of terrible advice. I'd like to echo goatsnboots: stress and time are your likely culprits. Can you free up her evening? What does she spend time doing after work? Can you do those things, take them off her plate, and see how she does with a few low-stress days? If she's warm/open to intimacy, don't take a mile. Give only an inch (hah) and let anticipation do it's job. But seriously, don't go in guns blazing. Pretend you're dating again and ask for consent at each step (bonus to this: it's free sexy talk!), don't assume you know what she needs, and rediscover what sexuality looks like between you two.

Jumping to suspicions, or insecurities of any kind, will only harm things. Prioritize open communication, set aside time to either discuss or be intimate. And again, don't go full hammer if she's open to being intimate, take time to relearn what makes you both click.

How about audio recording yourself? Just press play on your phone and chat away.

My doctor put me on bioidentical progesterone cream, I use it the week before my migraine is expected (which is the same time that my period starts). Changed my life.

Is there a certain activity/playtime/craft/teaching that you especially notice the kids benefit from? Something that you plan to keep up year after year, a necessity in your curriculum?

Also, I had no idea that you would be getting so many gender specific questions - I didn't think it was a big deal to people. But it made me think: I had a male teacher (grade 6, mind you) and he was one of my most influential teachers of all time. I was thinking of him the other day and wished I knew how to contact him to thank him. I had another in grade 7 for two electives and he was equally as important to me.. I think having a balance of male and female teachers growing up helped me cope with having a very part time dad. Everyone needs a good father influence! So keep it up, you're undoubtedly more important to those kids then they know. Cheers!

Probably laser hair removal.. usually expensive but it's the most permanent non-surgical option out there I think.
