I need him back :(

So my ex left me. So this is what happened we started dating in January of 2017 a couple months into our relationship my ex sent me a pic of him kissing another girl so it made me upset and feel some type of way so I texted him, Brian(my ex) saw that I texted him and got really upset which of course so would I. We talked it out he forgave me we got back together but it just wasn’t the same so then everything was okay then I lied about following someone on Instagram and also about this kid being in a picture with me which like I was stupid to do that Bc like it was right there like he knew he was just seeing if I would tell the truth. So whatever again he forgave me, now that I look back st it I regret it like I took advantage clearly. So anyways so then a couple weeks later we like took a break and he went to jersey with his family for 2 weeks I was supposed to go but I didn’t so then the Wednesday he came back we talked and we’re going to work things out and then that weekend we went to his house in jersey and stayed the night and then the following weekend we went to Florida and then a couple weeks ago on September 28 he told me he wanted to be done and was done with all my bullshit. I texted him off this random text free app and he just kept not answering, he blocked me on all social media, blocked my number. So on Monday October 2 I decided to drive up to his college which is 2 hours away to just see if he would talk to me and give me closure we talked for about an hour and he never gave me any closure he just said he’s done and that he doesn’t know if he’ll ever want to see me again. So I had asked like can u just text me occasionally like before we dated we were friends and it’s going to be weird not texting you and he said yeah…so he ended up not texting me and I felt like a worthless piece of shit then a couple days later he did text me and just pretty much said like he’s done and that no matter what happens he will always love me even though he doesn’t show it or say it he always will. So I haven’t really contacted him since then and I went to a therapist the other day and he said to give it Time so I sent one last message to him and said like I’m going to give you space and he didn’t answer so just last Wednesday October 11 I called his phone and it said that he changed his number… so then yesterday October 14 I told my friend to follow him on Instagram and show em like his following and followers so she did…he’s following his ex on Instagram and like this other girl as soon as my friend followed my ex this girl requested to follow her so like is he talking to this girl… idk what to do! I need him back everyone keeps telling me time…but like give him time to get over me
