Texting in Relationships... & rambling. HELP

My boyfriend and I have been dating for 2 years now and we’ve gotten very comfortable with each other. When we used to talk in the first 6 months or so of our relationship it was obvious that we were into each other, sending long texts asking questions and really showing how much we cared. We live apart so communication is very important. Lately, when we talk, it’s small talk mostly and trying to confide in each other when we’re feeling sad.

We don’t sext, ever. We have sex maybe 3-4 times a month. I’ve caught him jerking off and looking up girls.

He’s not into me anymore is he?

We’re supposed to move in together next month, but I’m just not sure if I should...

We have been through so much, helped each other through a shitton, but I feel like there could be someone better out there for me. Should I break up with him?

Is it common to have conversations turn so blah after a while?

I’m so confused please help 😩
