I have some question for some long ltrs - like 3 years and more.

What if she rarely sends me nudes? If i ask she sends but never(or almost never) by herself. How to deal with insecurities? I suck at this. I hate those snapchat/instagram things. She does not post a lot but still, its a mine for woman, its just a message away for a fuck... how stupid is this?

Sometimes i go for couple days for work in another city (like 2 - 3 days top). When i come back i often text on my way - 'hey, what show did you prepared tonight? ive got wine' or something like that, she oftens respond something like "you did not buy me new lingerie so i cant do nothing( i never buy her lingerie or clothes), i respond 'ok, nude is better' Is she trying to kill my mood with that or what??
