The Essex reality star told Daily Star on Sunday that she was "happy, in love and moving forward" with Pete after agreeing to put his sexting scandal behind them.
Megan, 24, was left devastated when Pete, 28, was caught sending saucy texts to other women just six months into their relationship, including while he was on holiday with Megan.
Pete spent most of the last TOWIE series trying to win Megan back and, as part of that, gave her access to all his social media accounts. In the finale episode, she agreed to be official again and move forward.
Talking to Daily Star Sunday, Megan said: "Pete wanted me to have access to his Twitter on my phone to make me feel better but I don't need that reassurance any more. People can call me a mug for giving it another go but we are happy, in love and moving forward."
"Learning to trust him completely will be a work in progress," she added, "but I do believe he would never do that again or I wouldn't have taken him back."
Speaking in a video posted to the TOWIE official Twitter account last week, Megan said: "In some of the best relationships, something really sh*tty has to happen to make it get stronger. So I feel like whatever has happened is in the past now.
"We can put a line under it and move on and enjoy the rest of our future."
"I think it will be a good future," she added.
Pete agreed: "It's been a terrible time, but on the plus side I do feel like we can get through anything. Love rules all. I've said to everyone and Megan a thousand times I'd do anything to get her back. Obviously we are back together now, but that doesn't mean everything stops.
"I stand by everything I said. I do see my future with her. It's not just about trying to get her back, getting her back and going, 'great, I have her back.' It's about keeping her and that's what I intend to do."
"When we first got together everyone doubted us and said it wouldn't work," added Pete. "Then when all the s**t happened before, everyone was like, 'Oh I told you so.'" Well f**k off. It will work, it's going to work and we're going to make sure of that."
