@babybird,
Good thing is there is a inner consciousness of you. This reminds you of something wrong has had happened. This is a very good sign and an encouraging one. Trust me...I could only wish all the young people has this now-a-days.
Specifically pointing to your situation, the ball would be to completely avoid the other Guy. Rush of hormones (naturally ofcourse) may push you to him. Trust me, with in no time you will be completely out of this ****.
Do not text him, remove his identity and do whatever. Remember, that you are not doing this for yourself...but for some1 who places sooo much trust in you and loves you. And as the spark end, you love him too.
Take Care.
