It could be the stresses of life, or it could be that you're not feeling as confident about your body as you've gotten older--NOT saying you don't look great--I don't even know you IRL;), and also NOT calling you old...I'm 37! It might also be hormonal, so you should probably see the doctor just in case.
ETA: I just went back & read your comment about your weight.:grouphug:
I lost thirty pounds about two years ago by eating low carb, which I've kept off & I will continue to eat this way...otherwise I'll gain it all back. Before I lost the weight, I was not very much into teA b/c I felt so badly about myself. Losing the weight made a big difference in how I felt. Still, though, even when I was overweight, my hubby loved me & my body & wanted frequent teA. Your hubby, from what you've said, desires to be with you. If it's just your feelings about your weight that's holding you back, I hope you can put those into perspective and know that he wants to be with *you.*:)
