So you're asking when he'll come back? He'll come back when you're not feeling lack. He'll come back when you're consistently aiming for good feelings. Several times you've posted that you think LOA may be a joke. One of the things required is faith that it will work. Money, job, success or an ex won't come from a place of lack. If visualization didn't work for you, have you tried making a vision board, scripting, or RS? All of these techniques raise your vibe as well as help you believe in the reality you want to create. Can you give yourself 30 days and just believe?
As for signs, i would not put that much weight on them. They're an added bonus but not the carrot.

My question more or less is how long do you have to be feeling good before the good stuff shows up??

And I'm not stupid and I would really appreciate if someone/anyone can answer without trying to make me feel dumb. I wouldn't be asking the question if I already knew the answer

I've noticed you have pointed out many times in your posts that you are not stupid. And as a moderator I watch each and every post here and I've never seen anybody suggest that you are. Try to remember that you are always perceiving things through certain filters. And you seem to jump to defensive mode very quickly. I am wondering if this is your biggest manifesting problem? I read all of the advice here, and think it's totally on point.. but you read it and feel rather defensive about the info presented. It comes down to self worth. Most of the time, this is the case when people try to manifest a lover. I'm wondering if you should focus some more on how you feel about YOU? You must learn to let your defences down and feel wonderful about yourself before others can feel wonderful about you.

Your question is how long do you have to feel good before your stuff shows up.. It highlights the fact that you aren't actually feeling good yet. When you try to "feel good" just to get your stuff, the universe can feel your effort img, your doubt, your distress that it's taking too long.. so your stuff can't come. When you genuinely begin to feel better, you start to see things in a whole new light. And manifestations begin to occur very quickly. And you start to have fun. You learn to feel great about yourself, and you enjoy it so much you don't really notice the lack of stuff anymore!

No, the desire is still very much there, but from a high vibration your heart is full and you don't feel any longing or needing. You simply feel like giving and expressing and being. There's no worry or doubt, because you know your worth and you trust emphatically that what you desire is coming into your reality I the most wonderful way.
