Erm I was just kidding
I think Bex is just a crazy care free girl, and I'm not sure what she has done to Luke? But then I am not following either of them much at all lately. If Bex rates getting a silly tattoo as no big deal then that is because to her she wouldn't regret it. She would just laugh and be proud of it as one of those crazy things she did once. And she is right. We only live once and not for that long either, so what is the big deal? Can't be worse than snogging Mo on national TV
They are both a bit controversial and not adverse to going too far with things, Bex is just a bit more up for anything than Luke. He is a big boy if he thinks it is just not fun anymore he can always leave her. If he still appreciates all those things he loved about her in the beginning than they will carry on together. Luke and Bex don't like to bore us with their day to day. For all we know they still have those sweet moments together. Just because they aren't on live feed anymore doesn't mean their relationship is not as strong as ever.
I still remember the beginning of their relationship and I still believe that they are great for each other. People aren't always perfect though, we all have our negative points and when it comes to couples you just need to find someone who understands where you are coming from and accepts you for all that you are and I believe Luke and Bex are that kind of couple.
But hey I could be wrong and if so they can sort themselves out. I will still like Bex anyway because I appreciate Bex's spirit.
