When you first get together with someone, it might feel really great to talk to the person you're dating every day. Swept away by new feelings and newness, you want to stay connected to affirm your feelings for each other. You want to check in with them, tell them what a nice time you had the last time you hung out, and find out how their day went. Over time, though, checking in with your new partner every day can devolve into talking to them constantly, especially over text. Talking to one another constantly isolates you from the outside world. Conversations you might otherwise carry on with friends or even strangers all become channeled to your partner. In a healthy relationship, though, your social relationships don't suffer.
