Many times when we meet people like you tell, we make us "perfects" thoughts about how good this relationship will be.
Our feelings burn for it....and if allowed to develop will destroy the marriage you have, without you even have been out with this woman you fancy.
The "love feeling" is a known phenomenon in any internet conversation, and even if some can find their partner this way, most of the love feeling are crushed when they start to know each other in person.
I will give you the same advice I have given earlier.
Take a "time out" Be honest to yourself when you evaluate your marriage....the only person you fool is yourself.
Do you want to grow old with your wife....do you want to support her....do you think she will support you.
When you comes home..are you glad to see her?...or do you have the feeling of " duty towards her"
Do you both like to spend time together? Do you allow each other room for development of interest or hobbies?.
If you have been married for some years, we tend to go into a daily routine, which can seems to be dull and not that exciting it was when we was in "flaming love".
This will also happen if you change partner. What you know about your wife today.....you will only know about your new partner in some time, and maybe you don't like what you find then.....or maybe you want to try out another "flame".
In my opinion the only reason to change a marriage is if we feel ourself misused and there are no feelings left for the other person.
You know what you have....you never know what you get....just remember back when you started dating your wife.....wasn't your heart burning then too?
I wish you good luck
