There is such a thing as loving someone and being in love with someone and when you give it some thought you will know the difference and yes to be the last to know hurts and hurts deeply but once again if this can be any comfort at all this was meant to be there is possibly something better for you....and this should sure enough be a lesson for you not to let it happen again,not the same way twice,may this help in some small way,I see this question was posed2 months ago and hopefully things have somewhat smooth out.
I'm sorry to hear this, but in today's society it is very common for people to not "feel" the romance anymore. The truth is that love is about values. Even married couples have times when they absolutely hate each other. But that doesn't mean they don't care/love each other.
I think it's in the little things. Find what they are interested in... Or used to be interested in when they were younger but gave up for some reason. Find things to do together, like going for walks, or volunteering together. The more your common goals are similar the more you will grow towards each other, and hopefully rekindle a spark.
I also generally, remind people that romance isn't like it is "in the movies" and it takes a lot of work to be in a relationship. Perhaps sharing same spiritual values will ensure that your fiance is on the same page as you and won't have a repetitive issue with "falling out of love" with you, or anybody for that matter. People tend to behave the same over time, unless something drastic happens to change their ways. Try to communicate, and listen, and not judge. Good luck!
I would suggest that you take it easy. Give each other space so you will get to miss each other. Establish a routine so he continues to feel secure that you are there and not looking for someone else. Do not nag. Keep yourself busy....and beautiful. Good luck. I hope this helps.
I answered a question similar to this a while a ago and I will tell you the same. Discussing old times like when you two first met and how you felt about one another and what made you fall in love with one another. Maybe talk about what went wrong. But when this is discussed make it sound like your just thinking back not like your begging to get back with him. Talk about it with a smile. Be a little hard to get with him yet still available to him in a way. Still do small things that show him you still love him even though he may not love you. Like bringing him something home to eat. And keep up with yourself and how you look. And reconnect with yourself, show him you are your own person.
