Guys who suck at texting?

Dating this guy about 2-3 months now and he told me he sucks at texting and super introverted. I mentioned more than twice over the past few months my love language is affirmation and i would appreciate it if he could check up on me at least once a week and apologized but doesn’t text me much still. I’m honestly sad and not sure if he is not serious with me. But whenever our planned date comes up (we meet biweekly) he would text me to make plans and looks excited to meet me.

I don’t know how to tell him his lack of texts makes me sad especially when he put in a lot of effort in the beginning.
