Can the Libras please help me with this

If she is seeing someone else her heart already left you. It does seems that she is immature. Your best chance is just to leave her alone. She will only hurt you more if you stay with her.
There’s a lot of reasoning I could for her immaturity’s, I just don’t get how she makes it seem things are so good, telling me she loves me, kissing me and then this?
