I'm confused with my love life.
What are you specifically confused about?
I like one girl but I'm dating another.
That's not confusing, it just means you need to make a decision and be honest. It's not fair to anyone to juggle multiple women in secrecy.
I don't want to hurt either of them. So it's better I stay with them.
You should think about how you really feel and act decisively. At the very least, you should communicate with your partner that you have feelings for someone else. Being dishonest will only hart them.
