I know what the OP asked, my answer to that is no I just like whoever I dislike least. I thought I was quite clear..

Only sometimes and to a very limited degree. Those who always focus on comparing the house to real life on the outside really suck all the entertainment out of the show. The producers encourage it as I suppose it gets them more eviction phone vote money.

I don't know anybody like Jackie in real life. But I feel like if I was colleagues with them all, Jackie would be my BFF

Not really. I have loved housemates who are nothing like me like Rex and Aisleyne.

Sometimes people I hate at the start begin to grow to on me like Charley, but only because I begin to find them funny or because I see a softer side to them.
I thought that would happen with Sallie this year, but during that eviction night I actually felt disgusted by her and was glad she was gone.

I like Gina and I liked Ben Duncan too despite not being like them at all when it comes to wealth and privileges. However I found Ben hilarious, I also find Gina amusing and think she has a very kind heart.

Kindness is one thing that will draw me to a housemate. If I see a housemate show compassion or an attempt of friendship to another housemate in some way, particularly if it is towards a housemate that they don't usually get along with, or a housemate who is not that popular. Then they will shoot up in my estimations.

I'm beginning to like Callum more and more.

I liked Dan at the start when he split the girls apart in a lighthearted way by twirling Gina around, and also how he tried to talk sense to her in a calm way. He also seemed very down to earth and "normal".

He is starting to grate on me a bit now though, because whilst he does have perfectly valid arguments with people, he does have a very patronising and arrogant tone to his voice and it's starting to irritate me.

I also watched a clip last night of him talking to Jackie in the garden, and the way he kept calling her back with his finger up saying "come here now Jackie" in a really authoritative voice bugged me. It wasn't said in an argumentative way they were more in a playful mood, but he still just sounded very bossy to me to a woman who is his senior.

He's becoming a bit too moany. I don't strongly dislike him though, just hope he chills out a bit again.

TLDR;
So overall, no, housemates don't necessary have to be similar to myself or my friends for me to grow to really like them. (but sometimes they are)
