If the relationship has worsened, then you can think about a divorce. Perhaps with another person you will love even more.

 Recently, I've had problems with a girl myself--through inquiries of close friends and family members with similar experiences, I gained a new outlook on love. When you are with someone for a prolonged period of time and come to know them inside-out, an unconditional love manifests in you. Now, this isn't the type of love where you think about them at night or you fantasize over them. It is similar to the love you feel for members of your family: you care about them dealt and would be devastated if anything bad happened to them; however, you don't think about your affection towards them and get jittery. With romantic relationships, you have another form of love where you do constantly think about the person and get butterflies in your stomach when you are around them. I'll just call that "fun" love. Fun love is essential for a good relationship, but it isn't always present. Throughout being with someone, there will be many times where you lose that fun love. You may look at other people and become interested and you may even consider leaving your partner. In a healthy and caring relationship though, it is up to you and your partner to realize that the unconditional love is there and that it requires work and time to reignite that fun love. Unfortunately, many people neglect the beauty of that unconditional love due to the loss of fun love. I hope this helps in some way. Truthfully, I am trying to answer a question so that I can post my own.
