I feel like I am way more into my husband then he is me (idk if this is some postpartum problem or...)

I had my second baby 8 weeks ago and out of nowhere a week ago I felt different. Sad. Weird. Love taking care of my babies and being with them all day but I miss my husband all day and overthink so badly thinking about it he’s still in love with me and if he means anythinf he says or wonder if he’s thinking of other people. Idk why I am doing this. My last relationship was very bad and abusice but I have worked past those problems or so I thought. I have been with my husband for 3 years now and known him my entire life. I’m so in love with him but I literally talk myself into thinking that he’s not into me and that he’s just annoyed with me all the time. I literally feel so insecure about my body and i know I feel different when we have sex so now I always wonder if he’s thinking of somebody else while we’re doing it. Or if he’s bored with me. I’m incredibly moody all the time we are constantly arguing. It’s so unhealthy for me obviously. I had PPA with my first and idk if that’s what this is again or what.
