Wife turned kind of... asexual

So my wife was never really the part in our relationship, which took the Initiative , but with the (late) pregnancy her interest into intimacy was completly obliterated. During the pregnancy and 3 months after, nothing at all was possible (not even slightly petting) In the following two years we had about 6 or 7 times sex. The only thing that is possible now at a Daily Level, is caressing and massaging her backside on the couch and a good bye kiss in the morning (But only without grabbing her ass or something, while doing this, thats already too much for her)

Its not that she just doesnt like me anymore, its just that she almost never thinks about sex anymore (she told me so herself). She also doesnt masturbate (or has sex somewhere else..). Being honest is one of her core traits. What I can see is, that she doesnt like her body (she still has too much weight). But I do not care, I am a T&A man anyway and she has a great set. Of course I told her so, but it doesnt seen to help her.

One time she even told me in the morning, she had a sex dream and jokingly added "that should be enough sex for her, for the next few months". Well in the end it wasnt a joke... My problem with everything, she thinks about it a few times a year, I think about it a few times a day and its eating me up. (Yes she does know, that I think about it Daily)

Update: there was another low blow, just a few hours later. Both in the bathroom, talking, she undressing for bed time and walking around nude. Then she told me "dont look so much". Whats funny, in this case I was really just looking at her while talking, not oogling her
