We both like each other but she have a boyfriend

I had a crush on her since past 1-2 months then she left my city, that day she called me and cried a lot.

As we were connected through social media, we play online games at night and it goes on everyday. We both like each other and have feelings too(since 1st day).

Every night I told her about my feelings and affection and how much I love and respect her. She get happy by these little things.

But she was in a relationship with her boyfriend since 5 years and one day she caught her boyfriend cheating her so she was about to break up with him but there was a situation that both of them couldn’t be apart because the girl has been in a physical relationship with him and the boy don’t want to leave her. And after we meet and talk she told me everything about their relationship.

But the real thing is I know she don’t want to leave me although they don’t want to be apart for now also she always told me to wait for and if something happens with their relationship then she will move to next step or may be she’ll be with me in a relationship .

But it’s been 10 months now we’re re talking daily on video call and voice calls from the 1st day and and it’s getting closer then before. What should I do ?

Is it okay to be with her like this cause I get hurt sometimes when then get close or when she talk about him . Is it normal or what can I do?
(*She always get emotional and cries whenever I tell her let’s apart)
