Men get bored of a woman for two reasons:

1. She tries to change him too much and he "switches off".

or

2. He see's himself getting someone much better than you somewhere else.

Now the first thing to do is not to blame yourself. Those two reasons up above are from his perspective. It might be in reality that you are the best person for him, but he is having a bit of a brain fart and doesnt realise it, that is until you make him realise it.

Do you want to turn this around? It will take some work on your part, and really depends on whether you two are broken up already or not. If you two are broken  up then head over here for more personalised advice.

You see men are really simple creatures, they look so confusing because they are just too simple. We like some things, and dislike other things. When a person a man is dating does more things he hates than things he likes, it is then that he will resort to reason number one and "switch off".

Men resort to reason number two when you either over praise him, or he sees traits he believes means you are inferior (things such as laziness, stubborness). These are only drawn in sand however, and if a woman a man has previously seen as lazy is recently seen to be active the image will change almost instantly.

So how can you fix this? Simple really, the easiest way to fix number one is to focus on what he does right, and not correcting every single thing he does wrong. The ideal situation here is to seem like you have much more important things on your mind than whether he eats at the table with his elbows on it.

To solve problem number tow i want you to be active with your life, i am not saying go for a run twice a day, what you need to do is to find something that you love to do, and build the passion to be the best at it. If your man sees that he is not the centre of your life, he will be drawn to you, however if you try to make him your reason for living, then you are making sure that he will grow tired of you. But more on that later.
