There are many reasons people decide to marry...but not least of all for Love. Why did you marry?...If the reasons are that you felt sorry for her, or she pressured you, or for other reasons that made you feel obligated...then I would suggest you have a long talk to her about where the marriage is leading, and the reasons she wishes to remain married. Explain to her what marriage means from your point of view...and if your feelings don't align? then start thinking about moving forward without her. This doesn't mean that you don't care for her, Im sure that you do...but that usually isn't enough to sustain a marriage. As Lefty said 'Life is way too short'
