Womans point of view. I am a man

Kristen
Ok, I don't want to sound like a bad guy but here goes. Just give me advice please.so me and my wife have been together for a year and a half and our sex life is not what it used to be at all. She is 8 weeks pregnant. She has, over the past 6 months or so, not initiated sex at all. She no longer gives me BJ's or any foreplay. But when we do make love she just lays on her back and doesnt do anything. I am a pleaser. I do everything I can to her. Much of which she never had and she loves it. But when it comes to me she doesn't want to reciprocate anything. I will stay down on her for an hour and she will get off several times. But with me she looks at me and says "ok, I'm going to do it for a minute my jaw hurts." Or some excuse. That's a turn off to me. She never was like this. I approached her about it and she got mad at me and said well, maybe I could enjoy it more if I get off. I get her off about 7-8 times a week with oral. And I bought a vibrator to help. I know women are different than men in that way and need alot more emotionally. This is my daily routine with her, I wake up at 4 in the morning and get her lunch fixed, Ake her at 4:30 to get ready for her work. She leaves at 5 and I get my stuff ready and leave at 6:30. When she gets home at 6:30 or so....she works 12's, I rub her feet, have dinner ready and here recently have been running warm baths for her and rubbing lotion on her when she gets out....yes, baths, I know not to run a hot bath bc it could harm the baby. I do this daily and she never wants me like she used to.....what is going on? I want her to want me again. We are only in our mid twenties. Did she do all this stuff when we first got together just to keep me? I ask her about my "size" when we first got together and she said she has had a little bigger and a little smaller....I wanted to see if that was the issue. Then she admitted I was the biggest and the only reason she said that was she didn't want me to get a big ego and go cheat on her. I never would. Please help. Ask me anything. Advice?
