The current reality doesn't matter or exist.
You're developing each day.
The first thing you could consider doing is stop downing your abilities and stop focusing on the things that you don't want.
Stop watching his social media or whatever you're doing to see the other girl. She doesn't matter because the *slide* or *reality* can be changed but that's up to you.
If something negative comes up in your thoughts, re-block it as soon as possible to something positive.
Affirm that you're his girlfriend with a great relationship.  Tell the universe what type of relationship. Picture it so that you too know what it looks and feels like.

I failed once more, I bought him gifts. He called me for meeting.

He kept them though but with a very odd way.
Now without me realising we became that distant .
What todo now?
