I need some advice ladies. Or even opinions

I’ve been with my boyfriend for 4 years on and off. It’s been a rocky road and we’ve both done our fair share of shitty things. We got back together with the agreement that we would go to couples therapy. It’s been 6 months and I’ve been asking to schedule an appointment. I haven’t been feeling right, my feelings are fading & I feel like I’m sleeping in bed with my friend. He’s changed how I wanted him to and he’s been great, super affectionate and all. But I don’t feel affectionate towards him anymore. I don’t even want to have sex with him. Do y’all think couples therapy will help how I’m feeling? I can’t seem to forgive him and let the past go, while he says he forgives me for everything and put the past in the past. Has anyone been in this situation and couples therapy helped?
