הכרויות נשואים|להכיר בחורות

She's (29f) my (first) girlfriend for 4 months now. I just only recently realized that she always has an earphone when we go out. It could be a dinner date, morning breakfast, amusement rides, going for some korean bbq in the evening, shopping or just going downstairs to our apartment lounge to chill, play pool, etc. I noticed going through our pictures that she usually has an airpod in - listening to music

I never mentioned it as it didn't bother me but I wonder if me being so nonchalant about it is signaling her that it's okay to be half present to me? Would you guys consider this disrespectful ?

When I think about it logically, it seems pretty disrespectful to be out with your partner and you're listening to music, especially if your partner planned everything, took you out and paid for everything, the least you can do is give them your undivided attention, right?

Could it be that it does it not matter to me because I don't respect myself and I have low self esteem? Or am I just a chill guy? This is also my first relationship

Also, we've had many arguments already, often due to things that I considered disrespectful to me and I did try to address those things.
