The question i see is you have to ask yourself…’What do you want”????. I dont know your past relationship either to know what happened or why you two broke up in the first place or anything like that so i cant really comment in anyway, but my personal opinion is there is no harm in having a little chat with him and seeing what he was wanting.. Thats only if you want to go back there weather its to hard emotional for you and what eva happened between you to, but i dont see why you can msg him or call him back because it could be for any reason, but you wont know that until you speak with him…How ever you are feeling just please think about yourself first and making sure you know what you want before considering someone else, 🙂 x
