Texting in a 2 year relationship

Ra

My guy and I have been together 2 years and some change but recently I noticed our texting pattern has changed. I read a lot on the internet that texting too much is bad for relationships and guys find it to be smothering after a while. We used to text nonstop and now it’s not as much and he doesn’t use as much emojis. He’s in his late 20s and I’m 21, I know I sound childish but it’s just my insecurities acting up. When we hangout in person he’s still loving affectionate and we have a good time together which I know is more important. Because I’m scared that he’ll lose interest because he’ll want to have fun text conversations with someone else like thats that bad scenario that I picture. But is it normal for the texting to not be the same? should I bring this up to him? Is it our 7 year age difference which is why it’s a big deal to me than it seems like to him? I need answers lol
