Should I officially break up with him?

I've been dating a guy for almost 2 years, we met in uni so we saw each other almost everyday. When I went back home in the summer he didn't bother texting much or even calling. When I text it takes him over a week to reply and the excuse is he's busy. He does have a job but no one is THAT busy. He also got caught cheating in an exam so he got a year's deferral which means I won't see him for a year. We texted a little but now he suddenly stopped replying all together, I've sent him multiple texts and it shows that he's read them. On whatsapp, I can see that he's online everyday but he doesn't bother texting me. He also wouldn't add me on snapchat which is a huge red flag for me. It's been almost a month since I last heard from him, so I assumed he was hinting that it's over. I met a guy in a bar a week ago and we hit it off and I told him about my ex. He says that it's over between me and that guy and that I should just delete his number and move on. However, my friends say that I should at least text my ex saying it's over. But since he's been ignoring me for a month doesn't that mean its already over? He also "burrowed" a lot of money from me which I doubt I'll ever get back and I don't plan on asking for them. I'm surprised how good I feel about breaking up, although it's been less than a month. My ex was very possessive and did't like it when people disagreed with him. I lost so many of my friends because of his temper. But he'd justify it saying this like "Trust me, they're jerks, you're better off without them, you've got me." People warned me this would happen but I was too drunk on love, as people might say. Anyway, my question is, do I text him saying its over or just delete him number and move on???

Forget about him. U should be concerned with your present guy. He is the one that matters. Tell him the truth about your ex-relationship. **make sure u tell him u have forgotten about your ex. Text him and make sure he receive your message. Give him no room to explain or beg for forgiveness. But never make it an awkward moment. It should not be like u hate him. I bet he has already moved on without u.
