I think I’m a bad Sub/Person

So for the past 3 ish months I have been talking to a Dom strictly online , and they are absolutely amazing they check all of my boxes and I love talking to them. We speak almost every day and almost every day they tell me how much they like me and I reciprocate that feeling. The only catch is they are long distance and we haven’t been able to meet in person yet. We often talk about how if distance wasn’t an issue we would probably be partners and a couple irl.

However when we last had that conversation a few days ago I was told that they are strictly my Dom but they really like me and don’t want to share me, but have also in the past told me if I find something in person to go pursue it although they would be sad.

While during this time/slightly before I met this dom I had begun reconnecting with an Ex who I had very intense and hard to control feelings for, but hadn’t spoken with in over a year and dated in over 2 (who is also now long distance). And last night me and my ex were talking and the tone in our conversation shifted from pleasantries and catch up to real conversation about us and what happened and how they feel. One thing led to another and they started heavily coming on to me which I tried to politely push down by saying I’m going to bed and all that. But I finally had to say blatantly that I don’t feel comfortable, while I’m not dating someone I do have this dom and it would feel wrong. They said they didn’t want to intrude, but did not want to lose our reconciliation. I said I don’t want to go back to not talking either and went to bed, anxious about everything.

When I woke up this morning, I texted my dom and told them everything that happened and I was in an emotional crisis over this and had to cancel our evening plans and I need some space right now to think. They were very understanding but I just feel horrid, I’m just lost I don’t want to hurt my dom , but I very evidently do have feelings for this other person , who it didn’t work out with in the past. I had an emergency meeting with my therapist and they said I need to know how the ex felt and I asked them and we are planning a phone call to really talk about it.

I’m just so lost I have 2 people I really care about but I don’t want to hurt or disappoint either of them. I have been open and honest with everyone involved but idk what to do.
