The 29-year-old, who is the new face of hair extensions Easilocks, told us: "I haven't seen or heard from Alex in six weeks. Through him not contacting me, he doesn't even know where we both live.
"He's welcome to come and see Dolly on the days we've arranged, but other than that I want to get on with my own life."
Asked if 6-month-old Dolly would recognise him after six weeks, she said: "Probably not now, which is all his own fault.
"We've got schedules in place that he comes every Sunday and Wednesday, six hours each day, but he didn't turn up.
"He didn't turn up the first time, or the next time, or since... he just hasn't rung me or anything. I've got all the emails saying, 'Where are you? Are you not coming?'
"It's really sad, but I'll just make sure on my own that Dolly has a nice life so she doesn't want for anything."
Asked whether Reid pays childcare, she said: "No, nothing. It's a real shame because I actually found a receipt of his for various sex toys, well over £500 including a f**king chair, a..." before her PR cut in and stopped her.
Reid recently accused Houghton of making him sound like a 'sexual deviant', to which she said: "I wasn't the one dressing up as a woman and using sex toys. I think he made himself a sexual deviant on his own."
On befriending his ex-wife Katie Price, she said: "None of my friends can identify with anything like this, so to be able to speak to someone who's been through exactly the same thing has been a massive comfort. None of my friends could get their heads around it, to be honest."
Although Reid has insisted Houghton knew his sexual preferences, she said: "It's his oldest trick. He said that about Katie as well. Had I known Alex was like that, I'd have never been with him.
"It's fine whatever you are - whether you're gay, bi, you dress up as women - do that, but you need to tell someone before you start a relationship with them. You need to be honest because he's now shaped my future without telling me who he really is."
Talking about the rumours that TOWIE's Bobby Norris has been sexually linked to Reid, she said: "That's not weird, is it?! That's normal considering the other stuff he's done."

Back to her glamorous best, the former Celebrity Big Brother star said that she's come out stronger than ever. She said: "2013 is a new chapter. I went through a stage of not looking great and not caring.
"I got to the stage where I couldn't even be bothered to wear any make-up but now I feel like I've got my mojo back."
And her resolutions? "Make more of an effort when I go out, not worry so much about everything, eat healthier - and drink more champagne!"
She said of her critics: "You're right, I am famous for not being famous - even more so because I went into Celebrity Big Brother pretending to be famous but I'm glad I do what I do.
"It is what it is and I love my life and am very grateful for everything I've got out of it."

On future projects, she said: "I've got a TV show coming up which I'm really excited about, my own baby range, a jewellery range and I'm going to write another autobiography as well."
The original Essex girl said of the live episode of TOWIE on Monday night: "It wasn't the best, was it?"
And on the fact that they've coined her catchphrases, she said: "I'll let them have them - they're younger than me!"
