Hello Tessa, you did the right thing in reaching out.
With your emotions on the fritz, what you need is an infusion of the truth. Contact him and level with him. Tell him exactly how you feel, and just ask him outright if the two of you have any chance at being together again. If he says yes, go for it, if he says no, then move on and live your life.
The meaning of life is to give your life meaning, nobody can do it for you, and it is the most severe form of neglect to presume to live your life for the sake of someone else, (Excluding the raising of a child), or to make the worth of your life dependent on another person.
If you feel the need to talk to someone, or if you feel you might hurt yourself or someone else, do not hesitate to contact the National Suicide Prevention Lifeline at 1-800-273-8255, their lines are open 24 hours a day.
Please keep in contact and let us know how things progress. Never forget that you matter, and you are not alone.
