Re: the whole Jack Tweed thing.
I think it was lovely that she had someone there for her during some of her pregnancy (bearing in mind tthat the one who should be doesn't seem to be bothering!) Every girl needs to be hugged and told they are beautiful particularly when they are as vulnerable as we can be during pregnancy. I think it says a lot for Jack Tweed that the fact that Chanelle was already pregnant was not a factor in them becoming close.
But he is so not ready for any kind of stability and yes he can be a bit of a so and so at times but he has had his world tossed up and down and back round again. That is hard for anyone to deal with but at his age and maturity...
I think she did the right thing, and at the right time, when she decided to stop anything further happening. She knows that she needs to concentrate on the baby and herself right now.
Before long she will be a very yummy mummy and the guys will be knocking the door down for her. I think we may also see a change to the men she goes for as her whole outlook will change once her son is born and her wee boy will play a huge part in her future relationship choices.
