If you've already had success then I don't see any harm in contacting him just do it with no exceptions and don't be disheartened if he doesn't reply, just carry on doing the techniques.
All the best 😀
I have had successes with Lanies PW and BWD meditations, in fact I manifested a conversation between my POI and I and we saw each other last weekend. I was beaming with excitement!! I have the perfect opportunity for my POI and I to hangout tonight, but I do not know if I should contact him or not.. should I do some meditations today and contact him, or should I just continue doing my normal routine of meditations (knowing I'm constantly on his mind afterwards) and let him contact me, whether it would be tonight or in the near future?
