Unintentionally purchasing a heart shaped doughnut on Valentine's day

Q: I bought a donut from Dunkin Donuts because I was hungry and it ended up being heart shaped because of Valentine’s Day. I do not celebrate Valentine days and did not know that it would be heart shaped. I was not sure if I should return the doughnut but did not want to waste food so I ate it. Did I commit kufr or a sin ?

Footwear of ihraam

Q: I am planning to go for Hajj in 2020 but not sure what kind of sandal I can wear when I am in ihraam. I found that some of them are saying I have to wear a slipper with the 2 belts (flip flop) without any stitches. Some say that I can wear any kind as long as the back and the front are open and some say that it cannot cover the middle part of the foot. Please  explain to me what kind of footwear I can wear, if possible a picture would be great.

Husband saying "he does not want to continue the relationship"

Q: I got married in 1995. In 1998, my husband said on the phone "If you don't come by tonight's flight we will not be able to stay together, but as flights were not available I could only reach the next day. My husband did not intend to divorce me.

1. Is it counted as one divorce?

In 2002 we had to sign a court paper in America of divorce due to some official issues but we asked a clergy if this will be counted as divorce and he said no. After making sure that it does not affect our relationship we signed the papers, and stayed afterwards together as husband and wife.

2. Is it counted as talak?

In 2003, after a fight with my husband, he sent me mail saying that he does not want to continue the relationship but he did not use the term talak, but he intended to give talak. We are staying seperately after that but we spoke to each other atleast once or twice in a year as some mufti told me that I am not divorce and to keep the relationship I should be talking to him. After that I consulted many muftis to know if our relationship existed but some said that it existed while others said that it did not.

Please confirm as we want to stay together now after a lot of hardships for many years. We are trying to stay together but because of this being not clear we are not able to continue our relationship. 

Woman wearing fancy dresses

Q: Can we wear fancy clothes according to Islam? Fancy clothes as in long maxy dresses which are loose, the sleeves are full and the legs are not visible. My father says that it’s not allowed in Islam and causes gunah just because it’s a bit fancy. No body part is visible except for the face, yet he calls all my dresses inappropriate. Can we not wear fancy clothes on weddings?
