Questions pertaining to talaaq

Q:

1) When I said things like "if until then this doesn't change, I go and leave you" , really intending to leave then and divorce, and no change took place until that time limit, does a kinaya divorce take place or a sarih? This happened many times. I didn't know that ruling back than.

2) I really left her some weeks ago with a real intended kinaya divorce upon which she asked " are you serious? And I said "yes". The following days I talked to some persons and said things like "I left her, I divorced her, my ex-wife, I dont want her back..." ....while I had thoughts like "you divorced again by that....its over anyway", but didn't care because I really was thinking it's completely over anyway. So I learned in the hanafi school that if you follow a kinaya with a clear sarih then both come into effect. But the contract broke somehow with the kinaya divorce before anyway. So how to understand this? Is following a kinaya with sarih meant that it happens in the same sentence or sitting? Is this all relevant anyway if in question 1) contract broke before.

3) If you say unintentionally words to yourself that pop in mind like "triple talaq", is that a Problem? Like a song comes to your head and you unintentionally utter the words.

4) If in the aqd it was agreed that wife can any time make use of divorcing right "khula"......does that come in effect if wife for example said like:" if until then this doesnt change we separate " and both agree but no mention of khula ? We wish to reconcile with a new aqd. Is this after these scenarios still possible?

Walimah and reception

Q:

1. Should a nikaah be performed on a Friday say after Jumma salaat can the walima has be held on the Sunday?

2. Should the groom not have enough finances to host a walimah, can the boy and girl have a joined function where expenses are halved and both parties contribute?

3. Should the groom not have finances can just the walima be held?

4. In today's time there has come about a thing of reception which is held after the nikaah but before the walimah. Is this allowed ? And should this be allowed? Can it be that there is a Friday nikaah and Saturday reception but with no walima?
