Resisting it at all costs

So after my friend comforted me i started to like him again(this is the third time) and i yelled at myself that i can't lead him on so i blatantly said to him that i could not date him for a number of reasons, one being that he has a girlfriend, albeit in a very shaky relationship. He still likes me and he said the sweetest thing any guy has ever said to me. "You know i like you and just want you to be happy". I almost cried.
I started talking to this other boy who asked if i was ok since i left early from dinner the night before and i said that yes i was but i know(did not say) that this wouldn't last forever and that i would soon plummet into another brief period of despair that will require all my strength not to do something harmful so i turn to candy and my best friend. this is a good time to turn to Him as well but sometimes i forget and i just pray that i can find the strength to keep going. my friends have not yet gotten tired of me but it has only been a month and although they are living with me, they have yet to see this once a month every month for a week at a time. We shall see.
my roommate who has become like a sister to me is leaving at the end of the semester but i know she is not meant for this type of college and will find it easier elsewhere. We will text a lot and she will come visit but it will be hard because she just listens and knows exactly what to do even though i may not know how to help her except for prayer.
This boy who i was talking to is scary but of course i like the usual bad boy and although he isn't religious and says he could never be i am praying for him and trying to help with anything i can. The sad thing is he likes my bff and she won't date him because of his wild antics that remind me of my ex in the slightest although more dangerous.
I have also been offered to move rooms into the room with my bff but there are several things to consider: leaving my current roommate, her suitemates are crazy but are toning it down, having my own room has it's upsides and i have started to get comfortable. this is a difficult decision and i can only hope that the decision i make will be the right one.
