He is keeping the door open and playing ghost. Which means he wants you available for his sexual desires only. I hate to be the bearer of bad news but the only sparks that flew were yours my dear. If you still feel the need to follow through with him and try to get validation from his side which I will add its probably not going to happen because again if he tells you the truth that means he knows he will have that sex line cut. I would ignore him and see his reaction if he contacts you only in time of a sexual fling and shows no other interest in your life like your, day, hows your job going, etc. or makes plans for a date without sex then at that point you have your clear answer. Please trust your instincts if your asking you should already know the answer. A relationship is not a guessing game its a for sure thing!
