I need advice about my mother

I’ve talked to my friends already and they told me I did the right thing. But I feel awful.

I made my mom cry tonight.

I’m 30 weeks pregnant. I have my boyfriend and my mother as my biggest supports.

When we’re all together though, my mom flirts you can tell with my boyfriend. She will say things with a sexual undertone to him and ONLY when she’s around him. Never to me when me and her are alone just all 3 of us. i feel really uncomfortable. So I told her on the phone, not in front of anyone,hey that makes me uncomfortable I don’t know if you realize you’re being inappropriate but it makes me feel so awkward. I know she would never do anything but I feel like she’s so out of line. I am starting to resent her and wanting to cut her out of our lives. Which sucks because I love her but I hate the way she acts around him. We will be talking about thermometers because I had a fever and she said “ANAL?!” so loudly. Or another example, my boyfriend commented “you’ve been getting a lot of sun” to her and she lifts her leg up so high and is all seductive and says “oh but not on my legs”.

She’s like “What?!?! I didn’t realize i was doing that.” Started crying. I apologized I told her I didn’t want to make her cry I’m really sorry but I needed to say it.

Ladies. I feel so awful. I don’t know if I’m in the right because I made my own mom cry. Or are these hormones are truly messing with my head, because this pregnancy definitely has made me somewhat insecure. I’m losing my mind please help.
