In time, you will find that the separation gets easier for you. You adjust and discover that things aren't quite as horrible as you feared that they would be. And you get used to be alone and to accept what has already happened. It took me about six weeks to move on from the constantly miserable stage to something more tolerable. Of course, that was after several months of the absolute joy of in-house separation. It also took my spouse about six weeks to find out that separation wasn't as rosy as expected.
I also wouldn't read too much into the declining number of texts either. My spouse stopped texting me almost entirely and then started to tell me that she missed me constantly.
