<human>: Can you provide a brief rundown of the text in within 3 sentences?

I (32M, HL/NL) living with my SO (39F, LL), not yet a DB, but probably getting there. My SO is divorced with an 8-year old. Her previous marriage was DB after the birth of the child. She had a string of adulterous affairs before we met. Initially, we were in an LDR, and sex was daily whenever we met. But ever since we moved in together, sex has been tapering off and now it is barely a couple of times a month. I tried talking to her about it and she blamed me for wanting "too much sex" and that she could not keep up with it with the child and all the housework. For the record, I do more of the housework than she does.

I still initiate sex often, and she rejects most of the time - sometimes even because she wants a cup of tea at that moment instead. She would gently push me off when kissing, and give me a lame excuse.

I tried withdrawing completely and not initiating sex at all, but then she complained about me being passive, not loving her, and not working sufficiently for the relationship.

Once, she asked me if I wanted a quickie during the day. I was ready immediately, and she made fun of my eagerness, portraying it as desperation.

Besides the dwindling sex, non-sexual physical intimacy is also quite rare. We don't sleep together. I'm lucky if one kiss in a week exceeds 30 seconds.

I'm not yet thinking about getting out of this relationship because she has already been through a divorce. Also, the kid from her previous marriage absolutely adores me. Not sure if I must resign to this state for as long as I can, or face rejection repeatedly, or anything else.
<bot>: Me [32M] with SO [39F] (she's divorced with an 8yo child from a previous DB marriage) have dwindling intimacy and heading to a DB. Advice?
