Husband isn't Interested?

What do you think are the signs in your marriage that tell you your husband is no longer interested in you?

Sometimes I feel like my husband only loves how much I love him. And I feel sometimes that his love and affection comes from habbit...

He really doesnt put much effort in our marriage. Whereas I am constantly listening to Ted talks, podcasts, youtube videos, reading books, article's etc on self and marriage improvement. He gets upset when I mention improving or changing our marriage..

If I get really serious, he will change his attitude for 3 or 4 days and then his back to normal.

Our sex life use to be great and it goes through stages when its great but that is only when i seriously bring up not being happy with our sex life.. and again, a week later.. its the same old situation.

Sometimes I feel like he just doesnt care about me or our life together..

Tonight for example.. he was staying overnight at a hotel 2.5 hours away and I was driving back from my mums house which was 1 hour away from our home. It was 9:30pm and there are always loads of kangaroos on the road and its dangerous. I spoke to him on the phone for 20 minutes and when he wanted to hang up, I asked if he could wait and speak to me for 15 more minutes cause i was nearly home and i felt safer if we spoke, he said no and we said goodbye.

It makes me upset that he didnt tell me to drive safe, to let him know when I'm home or anything like that.

This really spoke to me because i felt like he didnt care at all...

I need some guidence from people who aren't family so if anyone can give me some advice or their experience if they have any.

Thankyou
