Boyfriend giving me the ick ? Help ?

I need some big sister advice/help.

My boyfriend is the type of guy who is very busy throughout the day and doesn’t text much and at first it bothered me but I soon became accustomed because I know people have lives and work. Since being accustomed to this I have been working on myself more in that free time and I’ve been doing good I don’t get upset if he goes the whole day without texting me, we have different work/ sleep schedules. But lately he has been upset for whatever reason and he’s being so affectionate with me and texting me so much and I feel absolutely suffocated now. Which is crazy because that’s everything I wanted in the first place when I started the relationship but he wasn’t able to give me. Now that he is giving me all this attention it’s giving me the ick like I’m physically repulsed by it and I have no idea why ! Like I just want him to go back to not texting me so much 😭😂 I’m completely turned off from him now. Does anyone have advice as to why I’m reacting this way? Or what I should do? Have any of you felt this before? I talked to my therapist and she said it’s normal to not care for people as much when you’re in a stressed state of mind because you’re not happy with yourself but I feel perfectly fine with myself so I don’t think that’s it. Thank you!
