Need some urgent advice

Hi,

I am in need of some advice here, I am married and we have a child, the problem is that it has always been a rocky relationship. I recently made a new friend at work, slowly but surely over a period of 1 year we grew quite close. I started to spend more and more time with her and we even have started to call each other and text outside of work hours.

At first I did not think much of it but as time has gone by I have become very fond of her and feel very attracted to her. Her first language is not English and so we communicate in Spanish as I am also a native speaker but British born. She knows that I am married and for that reason she and I wont cross the barrier. The trouble is that she is now due to leave the country and back to Spain tomorrow and the chances are that I wont probably see her again.

On my last conversation with her she mentioned that it will be too difficult to stay in contact as I am married, she is very decent not trying to overstep the mark.

I suppose want I feel I really want is to remain friends with her, but it will be difficult with regards to my circumstances as my wife has always been very jealous when I have had female friends in the past.

I am finding it quite hard as I got on with her rather well, but I cant sacrifice my marriage and I could not put my child through that.

What can anybody advise here, should I call her before she finally goes and let her know my feelings or totally avoid the situation?

I should know this answer clearly, but it has been awhile I have felt this way and I feel very confused.

Any advise will be appreciated.

Thanks for reading.
