Their issues are hard to deal with.

LOW self-esteem people are bad at communicating

Stop talking, let's just KISS

People with low self-esteem tend to be terrible communicators. They won’t come out and say what they want to say. You will have a very hard time getting constructive comments, from them..
Very often it becomes a up hill battle  to get to that happy place in a relationship if the other person has issues, they have not resolved... but they expect you to just understand..., without an explanation, that their long time issues were caused by many factors. Mom did not make them feel special, daddy was never present. Old boyfriends were not kind or caring. Ex husband was a drug dealer...And the list goes on.
How do you deal with it without having the proper training? Simple answer: You don't try to fix what you can not.... because you can make matters worse for the person who sees themselves as a victim in ever scenario.

Every door, to a person's persona  has a unique key. You can't  unlock their issues if you don't have the right key.... You may think you can pick the lock but. ... you may find out that what's behind the lack of self-confidence is not something you are ready/capible of handling.
The many issues are more that you can relate to.
If you are determined to try... then good luck! You are going to need more than luck.


Here is Why Some Can’t Have Love With Low Self-Esteem

Maybe you are trying too hard
To show me you love me!

You can’t even recognize real love

You don’t even really appreciate a great partner because you’re so unhappy on the inside. You may not even praise or thank your partner very often, because you can’t even feel their love.
You are not fully aware of what's happing, but if your partner has a sixth sense they might get you to talk, every now and then, about what's troubling you.
It not easy.....but if your partner likes a challenge this one is definitely a"Whopper"

Now I don't want to make it sound like I would run from these types of females .... Actually my experiences of trying to help has not always helped .... actually in some cases may have made things worse for them after the breakup!
