Those situations where Talaaq does not take place

Q: I was like kind of attracted to my sister in law. About a year back my wife and I where having an argument. She was telling me that she does not like me talking to her sister and that I'm always talking to her sister etc. I always like had the thought that the rule regarding where a man touches his mother inlaw with lust nikah breaks may also apply to the sister in law also. I also had doubts as to weather rule may apply to the sister in law. I was not completely sure. Anyway, during that argument I told my wife "you know if I even touch her (my wifes sister) nikah breaks" with no intention of any talaq at all. I wasn't suspending or issuing a talaq I wasn't even thinking about talaq. I just told her that for it to seem as though that is the islamic ruling. I just guessed/made up/ lied for it to seem that that is the islamic ruling and for her not to worry and to give assurance. I had absolutely no intention of any talaq, the only intention I may have had was not to touch my sister in law because its a sin. After couple of months I touched my sister in law with lust then after a few months I may have touched her with lust again. Some muftis told me that no talaq takes place because I had no intention. Another told me that no talaq takes place because that's a completely wrong statement and the statement won't take effect coz that's not the masla etc. Another told me it like falls under explaining a masla. My question is (1) is there any suspended talaq in this situation? If yes how many talaqs take place?  Am I safe and do I have anything to worry about?

Q: I have a serious problem with waswasa about talaq. this has turned into a mental problem like obsesive compulsive disorder where these thoughts keep playing in my mind and sometimes I think I say it on my own in my mind. I have no control over it.  Numerous muftis have told me that talaq has to be verbal for it to be valid. After getting fatwas from muftis then I get these thoughts that maybe the mufti did not understand or did not hear the question correctly etc and I go into a state of depression. This is really affecting me. Whether I'm doing good or bad I get these thoughts. I am in constant fear of talaq. Its like almost always playing in my head.  My question is (1) as I said this has become a mental problem and because of this I sometimes say things in my MIND ONLY  which may not be waswasa but because of this mental problem that I have developed  like egs: if I'm on the internet I say in my mind  "if I click on a certain link its  talaq". Then I just ignore what I said in my mind and click on the link and carry on with whatever I'm doing. Does any talaq take place like this? I was told by other muftis that no talaq takes place. Please advice. This waswasa is really affecting me. I love my wife a lot. May Allah bless our marriage ameen.
