I was married for 25 years, and experienced much the same as you. I made a vow before God and my family and stayed, even though I was tempted several times to leave, but he always begged me to stay and things would get better for a while, then always back to the same ol’ same ol’. He finally decided to end it 5 years ago and set me free! I met the most amazing man and finally know what it is to be totally and utterly in love. I actually did not believe in “true love” or being in love with one’s best friend, or “soul mates”. I did not think it was really a thing, but I do now. Oh, and my ex has regretted his decision.
