On last night's episode of the Essex reality show, viewers saw Lydia becoming tearful as she spoke about her on-off romance with Arg while out with co-stars Georgia Kousoulou and Lewis Bloor.
Lydia said: "Me and him had our little fling and both realised we weren't really going anywhere. I made my decision to go away for a month to South East Asia and had an amazing experience.
"I met somebody over there but nothing serious. He did find out I was going on a date. But at the end of the day, I stuck by Arg and we haven't been together for two years…"
Lydia began to cry as she added: "I've had massive strain on my family because of this which is probably why, as well, I have a short fuse at the moment. It's all a massive mess. I still want a relationship – just a friendship."
Last year, Arg was suspended from TOWIE because of his excessive partying. He later spent Christmas in rehab as he cleaned up his behaviour.
It was announced this week that Arg's suspension has now been lifted and he's back to filming.
Lydia was among those who had said she wanted Arg back on the show, saying: "He's doing really well at the moment. We're all hoping and praying he'll come back at some point during this series."
Arg did not appear in last night's episode but promised viewers they will be seeing him soon.
TOWIE airs Wednesdays and Sundays on ITVBe.
