What to ask yourself before going into relationship.
How are my personal insecurities going to ruin this relationship?
Because we go into relationship almost blind to our own wounds

And they resurface in the relationship and we blamed our partner for not providing medication for the wound that have existed before we meet them.
What I mean by that is that a lot of people who are financially insecure, will meet someone who is actually nice but may not be able to suit their financial insecurity, he/she immediately think they are not good enough.
Or you go into a relationship being addicted to pornography, and you meet someone who is actually at your right level, but because you are so used to hyper sexualised promiscuity that you think they are boring.

So ask yourself how are my insecurity going to ruin this relationship and how do I create a buffer so that this insecurity won't occur.
