Missing my EX

I miss my EX boyfriend. We took a break after a year and a half of being together because we both needed it. It was a mutual understanding. He was an amazing boyfriend. We stopped communicating everyday and drifted apart for a while. I miss him so much. I texted him and let him know how I feel and he said he feels the same way but he recently started talking to someone else and she lives with him and her son lives with him too. He said he was hurt/angry we took a break so he tried to move on. He said he thought I moved on too which I didn’t. It was only 3 months since the break and I always hoped we would get back together when the time was right. I never thought he would find someone else so quick. I’m still inlove with this man. He tells me he’s happy but it doesn’t seem like it from the things he tells my mom (he’s been in communication with my mom on and off since we took a break) I just found that out last month. he told my mom he’s not happy and he’s in a situation he shouldn’t be in. He also said That he miss me and miss being around the family. Another thing , He brought me gifts for my birthday that was in December and said he was going to ship them to me but never has because he wants to give them to me in person. If he truly moved on and is happy he wouldn’t be trying to do that..I asked him will we ever get back together he said he needs time and I never know what could happen in the future. I don’t know what I should do I’m not trying to ruin anything if he’s truly happy but I also don’t want to lose out on my chance with my soulmate. I think about him all the time and I look at out pictures and videos everyday. I know my post is all over the place but I’m so lost on what I should do... I’m just sad/hurt I don’t have my Bestfriend/my other half in my life anymore.
