The 'This Is What You Came For' hitmaker admits he found it "difficult" for something so personal as a relationship to "play out so publicly".
He told the October issue of GQ magazine: "It's very difficult when something I consider so personal plays out very publicly. The aftermath of the relationship was way more heavily publicised than the relationship itself. When we were together, we were very careful for it not to be a media circus. She respected my feelings in that sense. I'm not good at being a celebrity.
"But when it ended, all hell broke loose. Now I see that Twitter thing as a result of me succumbing to pressure. It took me a minute to realise that none of that matters. I'm a positive guy. For both of us it was the wrong situation. It clearly wasn't right, so it ended, but all of the stuff that happened afterwards."
Soon after the pair split, the 32-year-old DJ took to Twitter to claim Taylor was trying to "tear him down".
In a series of tweets, he wrote: "Hurtful to me at this point that her and her team would go so far out of their way to try and make ME look bad at this stage though. I figure if you're happy in your new relationship you should focus on that instead of trying to tear your ex bf down for something to do.
"I know you're off tour and you need someone new to try and bury like Katy ETC but I'm not that guy, sorry. I won't allow it. Please focus on the positive aspects of YOUR life because you've earned a great one. God bless everyone have a beautiful day (sic)."
