Idk if she loves me

This isn't a question... just a rant because I don't have many people I can talk to. I love her and the life we are making inside her. I want her to be happy with me. I do everything I can to make her happy and comfortable during her pregnancy. I want to marry her and spend our lives together and she used to say the same... but now she's so distant and doesn't show me any affection at all. She rarely says she loves me first. She doesn't hold hands or cuddle with me. She always seems like she couldn't care less if I was with her or not. She doesn't flirt at all with me. She used to send me Flirty texts but it never happens anymore. I think she wanted to leave me in the past but I thought things had gotten better. She was opening up for a bit but then shut right back down. I have never cheated on her or abused her at all. I give her 110% and just want her to be happy with me again. She barely even looks at me anymore... is it just that she's sick during the pregnancy? Does the nausea and fatigue really make you ladies push away from your sos? Some days I feel like giving up because I feel like she just wants out... I'm so depressed every day...
