Really don't give us many details on what is going on between you too. For example is she sleeping now with other men, or is it a case where you been pressing for it and so far nothing happened? But the way you said she told you she just needs her space, does not sound like a happy marriage with a loving husband and wife where she just wants to have a private place to go fuck in stead of motels or at your house. This sounds like a more serious problem that would indicate she is not very happy with you. I say this often enough but will again, loving some one means you care about them, being in love with someone means that you are the other half of who they are and the same applies to you. You can love someone and not be very happy with them. Part of a happy relationship is enjoying each other, still caring about them even when you might be angry about something that didn't go your way. I suspect there are a lot of issues you are not telling and my advice is best see what they are and get them worked out, cause your about to lose your lady.
