What have i gotten myself into?

They are getting closer and she likes him, he likes her. Soon, I didn't know where I stand. I knew it was the price I had to pay for asking him to go for her but suddenly, i felt like i lost everything. I used to be able to tell him everything anytime but now, i had to see which timing was suitable and day by day, we would quarrel and fight because of that. I hated myself, I thought i was able to take it, I thought i would be okay but i wasn't. I have never felt so hurt and jealous all my life when i knew that he was trying his best to balance both of us. PMS surely did not help as i gotten more grumpy during that period. I really felt sorry for him cause he have even fought physically cause of this. But he never left. He would always compromise with my dramatic scenes and just talk to me nicely. I really cant leave him even though everyone else asked me to. I loved him too much.
