His hesitancy is worrying me...

I am engaged to a man who isn’t sure about whether he wants to be married. We have been dating for four years and love each other very much, which is why I proposed to him six months ago, assuming he wanted to spend the rest of his life with me. He agreed at the time, but constantly asks me if I am sure, because he thinks we are being hasty. He isn’t backing out of the marriage, and our families are completely on board with this because they all accepted it a long time ago, but his hesitancy makes me sad. I don’t want to feel as if I am forcing him into something. What should I do?
If he feels as if things are moving too quickly, it simply means he isn’t quite at the place you’re at. Being in love is great, and the time you have spent together is undeniably meaningful, but this is a lifelong commitment that frightens a lot more people than you think. It doesn’t mean he isn’t love with you, nor does it imply that he wants to marry someone else. It simply means he needs a little more time to process this change and will accept it when he is ready. You can consider extending the engagement if it makes him breathe a little easier or continue having conversations with him about how he sees this relationship and what plans he has for the rest of his life. This doesn’t have to be a problem if the two of you air your views honestly and approach this with a willingness to make a few compromises.

My boyfriend recently sent his ex-girlfriend a message with a kissing emoji. He says they do it all the time because they are friends. Should I be worried?
Your boyfriend is with you, presumably, and not his ex. If you trust him, an emoji doesn’t have to mean anything serious.
