I went to twice a week after about two three months by my choosing because I didn't want to be in therapy forever. I was trying to get over a car accident at the time and I have multiple complex traumas from childhood through early adulthood to get through. I've been going twice a week for almost a year now and the progress is so slow even with that. It also doesn't help that I have DID from dissociate constantly. Twice-weekly I think helps me make maximum progress I don't think I would like to go 3 times a week I think that would be too stressful and I would feel like I was always in therapy. Luckily I do not have any inclination to become dependent on him or any kind of attachment to him if you do have those tendencies it might be an issue.

I have also started a DBT class about 2 months ago so I guess in a way I am in therapy 3 times a week just not with the same therapist. I only joined the class though because my therapist kept pushing me to do it because I have no emotion regulation.

If you have a lot to work through I might be helpful to go twice a week if you start getting too attached or dependent you can always push it back. I know if I only went once a week I would probably be in therapy 10 years or more and there's no way I'm going to let that happen.
