My advice... would be to start looking at your husband with "fresh" eyes... look at him... like you have never seen him before... and find... new things that you like... they are there... hidden but there...

If it is that you are just bored - and not abused.. in any way... that is...

The other side of the "fence" and perhaps something to think about.. as you go thru this.. I was married to a man that beat me.. for 12 years..

My son's friend's..... parents - they lived behind us... beautiful home.. in a beautiful neighborhood... his wife got "bored".... and divorced him.. 2 young children 8,5.... he made good money...
It was truly a case of boredom... by her... she was bored..

The divorce.. the home sold... she in/out of relationships.. the children torn apart....
Her "boredom" never got "cured"....

So... if what you have is comfortable.. in that it is not... abusive...from looking at their marriage and the outcome... I would say... look for the "new" within him... and you will find it..

I would have given my "eyeteeth".. for a "boring" marriage.... one that I could have "fixed"...
