We've been together a few months. She lives too far away to meet in real life any time soon.
I've shown her once what I look like but she wants to see more pics of my face which I understand but I'm someone who isn't comfortable with sending pics online, even if im close with someone.

She wants more face pics, she wants my phone number and some other requests that I'm uncomfortable with. I'm just careful on the internet, okay?

Besides all that, she got issues. She makes assumptions and jumps to conclusions about literally anything. For example we're haveing a great conversation, we having fun, at one point I say "ily" and her mood is ruined imediately because I said "ily" instead of "i love you" which to her is proof that I dont love her because I didnt take the effort to fully type it. This is just one example, another is when its 3am for me and I'm about to go sleep because its late and im tired, but she wanted to play a game or to talk to me, I say that I really need to sleep and then again she assumes I don't love her.

TO make a long story short is she often assumes things like

1. that I dont love her
2. that I love my friends / other partners (we're poly) more
3. that she is bothering me (though the only thing she bothers me with is this behavior)

Am I the asshole for being uncomfortable about sending more pics of myself? This is just something im very shy about, and i almost never show anyone online what I look like.

Am I being too careful when refusing to give my phone number? I love her, and we been together for months, but that doesnt mean I trust her, I trust nobody, especially on the internet. What can she do with my phone number anyway? I dont know, but I like to be careful on the internet.

But most importantly she is suicidal, and I really don't want to be the person who drives her to do it. What am I supposed to do? I'm for sure not going to break up with her because 1. I love her, 2. I'm scared of losing her, 3. she's suicidal, so I don't wanna do anything that could upset her. But how do I deal with this girl she has too many issues. I have issues myself too and maybe I'm wrong for not showing my face again or sharing my phone number. (and some other things)
