boy problems AGAIN

things r really rough for me rn which is fine I'll be fine I just need an outlet. I'm so exhausted & anxious and I'm just really really concerned and worried and idk I'm just not in a good spot haha I know I'll be ok I just am a very anxious person but stuff keeps happening and everything is just so scary. I like him a lot but he makes me a little bit uncomfortable he's flirting w me and he has a gf (that he is going to break up with)  and he's very depressed and suicidal and I just don't know how to help him he's posting and tweeting ab relationships and how he wants a big chested girl w black hair who wears bellbotyoms (that's basically what I look like/wear) and I get that he rlly cares and I'm glad for that but he cares too much almost yk? like tonight I tweeted that I needed 2 be alone and that I was ok and he got worried and showed up at my house unannounced (he lives down the street from me and walked over) and was basically like "yea I got a little worried and wanted to make sure you're OK and also I forgot to give u a hug earlier" and was telling me that if I needed to talk or anything g that his phone was on and he'll be there and I really appreciated that!!! I rlly did I just was very anxious and in a bad spot but idk. it's just there's do many red flags regarding him and yea I don't feel like I'm in danger or anything around him but like he just makes me very anxious. idk maybe im crazy? I just don't know ehat to do lol but o well ik I'll be ok :/
