Married but distant

Recently, husband and I started couples therapy due to marital issues, and we've been sleeping separately by his choice...I noticed he started to occupy the bedroom(not ours) more often since the 1st session and I can't help to feel he's pushed himself further then me...

Is this the storm before the calm? I know I probably shouldn't be too worried but some friends and family are putting suspicious thoughts in my head and I don't want to think that way...
