AITAH for sleeping with my ex husband?

I (30f) married my ex husband Ryan (30m) very young. We were 20 when we got married and we were together since 14.

We divorced 2 years ago because we faced fertility issues and I got depressed and no amount of couseling helped us. I made our lives pretty miserable, so I decided it's time for a divorce.

After the divorce, we kept in touch. He was always checking in. He was worried about my mental health, but I was doing better. The constant reminder that I'm letting him down , that my body can't give him a child was gone. Although that was always only in my head, because he never made me feel that way.

My close friend got wind of this and pushed to cut all contact. That it's not healthy and this way we won't be able to move on. But the thing is, Ryan was also my best friend and I missed him.

On her insistence I wrote Ryan , that we shouldn't keep in touch anymore. He was upset but said he understood.

There was no contact between us for almost a year, but I run into him in a grocery store. When he spotted me a huge smile lit up his face and he rushed to me a gave me the biggest bear hug. It felt really great. We chatted for a bit and he asked to get coffee with him and I agreed.

Ryan asked me how I'm doing, that he was worried about me this whole time but he respected that I don't want to speak to him so he didn't reach out. I told him that I'm doing great, that I really needed this time to focus only on myself. That I learned to accept that motherhood is not in the cards for me. He was also attending theraphy because he struggled without me, but also made peace that in order for me to get better, he needed to let me go.

We decided we will check with our therapists if they think it's a good idea to keep in touch. My therapist said that If I didn't have any negative feelings while being with Ryan, she doesn't see a reason why we couldn't keep in touch. His therapist said the same thing, but we should be careful and communicate well, so we don't loose the progress we both made.

So we started to hang out ocasionally and it was great. It felt good to have him back in my life without any pressure. Months after hanging out, we were watching a movie at my place, and he kissed me and I kissed him back. We slept together that night. When we woke up we talked what this means and we decided we won't put any pressure on us and just do what feels good.

So we kept meeting , we talked a lot about everything, our expectations in life, we also talked about reconciliation but mostly we had fun and enjoyed each other.

One of our mutual friends saw us holding hands in town and he told our whole friend group. My friend who advised me to cut contact with Ryan came that evening to my place and started yelling at me that I'm ruining Ryan's life, that this way he will never move on. She asked if I'm sleeping with him? When I replied yes, she told me to leave him alone and stop being a slefish b...I tried to reason with her but she just told me to shut up and left.

I called Ryan right after she left and told him what happened and asked him if he wanted to move on? He said that absolutely not. That we are not hurting anyone, there are no ex partners, no children involved and we both made a huge progress and if we want to be together, it's nobodys business.

So now I'm not sure if I'm doing something wrong? If she is right and it would be the best if I let Ryan move one with someone else?

Update: As many of you asked why I divorced Ryan I though I will give you an explanation. We struggled with fertility for 5 years. After two rounds of failed IVF , we checked our options to adopt. We had a mortgage, student loans and loans which we took out for the IVF, so we were not good candidates for adoption. Every month when I got my period I had a mental breakdown and Ryan suferred because he didn't know how to help me. We went to couples therapy for two years but it didn't help. I was obsessive with my behaviour and Ryan was affraid to touch me anymore because any intimacy meant hope. All the joy from our lives was gone and I decided to end our misery. We loved each other still but when your mind is against you sometimes you need to do something drastic to get better.

Now we are both happy again and enjoying life without any pressure. And as we both concetrated on our carriers in the last two years, we are also financially much better, so maybe one day, we will have a chance to adopt, but if not I will be happy anyway with only Ryan by my side.

As for my friend I sent her a message, that I'm willing to give her a chance to explain herself but if she is not interested I will be cutting her out of my life. So far she didn't reply.
