Will we get back together in future. he wouldnt lie?

If I understand your question, then he likes you but you feel he still won't forget the bad events of the past. If that is the case, he does need time. For every event needs some time for it to sink in. If it is just a tentative feeling of insecurity than it could subside anytime now. Everyone is different, some take longer than others to overcome things. If he isn't just feeling temporary insecurity, than he could of changed his whole outlook on you. He could see you and love you in another way than before. It is hard to solve this puzzle, but the only thing I can say, is to show him that no matter how he feels about you, you will always love him. Good luck and a Merry Christmas.
