I feel your pain! I swear this is my story, exactly! You don't say if there are children or young adults involved. I'm assuming the answer is No. Leo's are generous, romantic and loyal. The downside is that they are dominant, controlling and manipulative. You don't say what sign she is, that matters. Unfortunately, Leo's tend to stay in an unhappy marriage especially if they live a luxurious lifestyle and are treated like kings/queens. They love to be adored and catered to. It sounds like you both had the time of your lives together, however, as painful as it is, you need to focus on you right now. I'm a Virgo and we are people pleasers, we will move heaven and earth for the ones we love and it is unfortunate that other's see that as a weakness, then we wonder why we are taken for granted. I'm not saying that is what he is doing. We just don't know what the situation is at the present moment. Right now you are vulnerable and this is not the time to contact him, as a matter of fact, don't! Absence makes the heart grow fonder and if he really loves you, in time, he will suffer the loss and come back. Take care of you! Be nice to you! Go deep within and find your strength. It's there. It will make things alot easier for the time being. It starts with you first then things will fall into place. Hang in there, things will work out for the best. Good luck!
