Hey guys, I’m 25 M and i want to ask about my situation

There’s this girl in my uni that for a long time I have a bit of a crush with her. We have been both in some foreign languages classes together in uni but I’ve never talk to her before (So I don’t know her age specifically but she is in her twenties like me). For what I’ve check in her fb profile is that we both like heavy music and anime, also we both study kind of similar areas (I study philosophy and she study literature). Lately for the quarantine I’ve thought of text her on fb, but I’m really insecure about it.

To give more context about me,first of all I’m kind of shy, It’s not extreme to be honest, but I’m reaaally bad starting convos and stuff, but I can keep them normally. Oh also I’ve never date someone before, so there is that. My main issue with myself was my weight (I wasn’t obese but for a long time I’ve been definetly overweight), but lately I’ve lost 20 kilos so I have a bit more self confidence now.

The last thing I want to add is that also I don’t have really much the habit to text people. Like honestly via instagram, wsp, etc I literally write between 10 to 20 messages or less even per week I would say. Just checking up and asking or responding to specific things to friends and family. Nevertheless I want to give it a shot

So basically I want to ask if maybe could it be a bit creepy if I try to text her,(I don’t want to make anyone uncomfortable), how to avoid that if possible, what could I text to her and how to keep the convo going at least a while the quarantine is up where I live.

Finally sorry for my english, but it’s not my first language so i hope there is not that much mistakes in my post.

TL;DR: Shy 25 guy want to text a classmate of uni, I’ve never date before and I dont really text much. Just wanna ask what and how to text her to start and keep the convo going.
