Every person I ever met who was in therapy told me that it was the best decision they ever made. In some cases it can also be harsh especially in the first phases) as it can confront you with things you do not like to accept or even perceive about yourself.

In the end it is your decision, but given that your partner brought it up, you might consider doing it just for them. I have never been the receiving end of therapy, but I believe there is nearly nobody who could not profit from it in some way.
