Have I committed the unforgivable sin?

I cheated on my girlfriend months back. I felt convicted to not only confess to God. But to her as well. Anyways I asked God to reveal to her what I did. Because I was scared and needed some help confessing to her. Anyways recently she had a dream about me cheating. And genuinely thought it was a sign.
I had doubt it was from the Holy Spirit. But also had a weird feeling it was. Anyways, I downplayed the work of The Holy Spirit to keep my sin secret and to further my agenda. And told her lies like “God doesn’t do that anymore” etc.
this is what the Pharisees that Jesus rebuked did. When they committed the unforgivable sin.
Am I doomed? I don’t feel God’s presence anymore.
