Hello Jenine,
Like Anita, I’m wondering why you didn’t say something to your new friend about needing to focus on studying?
You say “after a failed attempt to get into the dating scene, I can’t stop thinking about him.” Is it him you’re thinking about, or just feeling lonely and needing a friend?
If you do reach out to him, I wouldn’t start off with an apology unless you sensed the friendship was moving toward something beyond a texting friendship – the reason being that what the two of you had might have been a blip on his screen and in fact he might not remember who you are. I would start with hello, and light conversation. And ask how he is doing. Go from there. You will know if an apology is in order based on his responses.
