Counseling?

In September, my partner and I will have been together for 8 years. The last 4 months, we have been struggling. Our communication has been off and we've been drifting apart. We both love each other and want it to work but we both also feel like we are close to the end. We have been considering going to couples therapy. Has anyone tried therapy? I am questioning going because I don't know if it is worth it. We are best friends and I keep thinking that we've gone through a lot and have made it this far for a reason. But it's hard. Does counseling work? It is expensive here. If we go once a week for six weeks it will be about $1200 that I will pay out of pocket. I want to marry him. Things turned sour so quickly. Do I give up all these years? A part of me feels like he doesn't want me but he wants to try and he wants to go to therapy. What are your thoughts and experiences?

We also have children.
