My girlfriend always looks at her mobile phone when eating with me, and she doesn't return my text messages when eating with others.

After a long time, the two people are too familiar, and there is nothing to say.

But girls and girlfriends have endless whispers that they may not want you to see.

What you need to mind is who she is in contact with, but peeking is not recommended. Feel free to ask.

If you love her, you must trust her. This is the minimum respect. However, it is difficult to solve the problem that you have no topic together. Two people together for a long time, the novelty disappears, and love becomes affection, which will all go through this stage.

If you want to improve, I suggest you surprise her with a little romance from time to time.
