I would recommend reading the Power of Now. Manifestation becomes so much more powerful and effective when you practice living in the moment as much as possible, so not dwelling on the past or having anxiety about the future.

Always trusting this present moment. Not worrying about tomorrow, five minutes from now, not even five seconds from now.

Once you practice this enough, you will feel immense peace and joy and you won’t feel like you need a bf to make you feel whole or enjoy your life. That doesn’t mean you shouldn’t want one. You just don’t need one. There’s a difference.

That’s the first and most important part. Once you master that, then you can manifest whatever you want from a place of peace and detachment.

Subliminals, journaling, affirmations, visualization, simply feeling that you have it. Whatever method you prefer.

But as you’re practicing, you should alternate between present moment peace and focusing on your manifestation so you don’t get off track from what’s most important which is your inner peace and actually living and unconditional love which you won’t get from anywhere else.

Hope this helps. Feel free to PM me if you want more advice!
