Need some help/advice

I’ve hit rock bottom and I don’t know should I believe in this manifesting thing anymore or not?

Context I was in a “situationship” with this girl, whom I started liking a lot and lot day by day. Didn’t play any games or tricks on her (which I mostly used to every time). Things got ruined and we stopped contact for atleast 5 months. In those months I tried manifesting. Got into Neville and what not and did a lot of techniques like SATs, visualisation and affirmations. Had some successes in between too.

After 5 months, we did started talking but it was started by me. I visualised her to text me. Every time whatever I visualise, happens, in an opposite manner. For eg, if I want her to call me, I end up calling her.

P.s. I’m quite impatient about this one girl and tend to check the 3D a lot of times.

Now, today morning we ended up on a bad note again though this time I feel hopeless. I know I’m my gut that she’ll be there in my life. I just don’t know what to do, how to make things work this time or anything.

Help me out guys.
