I’ve seen this happen and it always disappoints me. I’ve had arguments with some of my friends about this very thing. Here’s what I think has happened ...
When you were his friend or his girlfriend it was easy to tell his guy friends he was going to meet you and spend time with you. Now that you’re engaged and soon to be his wife, I suspect it is that whole ‘ball and chain’ rubbish some guys rave on about. Suddenly his friends might be encouraging him to not race to see you ... and may be talking about him being ‘under your thumb’. So he starts becoming distant.
For other guys, once they are engaged or married they start taking the girl for granted. They just don’t try to make her happy any more because they’ve ‘won’ her already.
Either way, if that’s what’s happening to you I believe you should see it as a warning sign of what to expect in the future. Tell him you agreed to marry a man who treated you well and he doesn’t seem to be that man any more. If he can’t be the man you fell in love with, why would you marry him?
I’m sure you’re looking forward to a magical wedding day and you’ve probably told all your friends and family you’re getting married, but it would be easier to end the relationship now than after you’re married.
If you raise the issue with him, he might see what a big mistake he’s making and change his attitude, returning to how things were. But if you’re not convinced, and fear your future together will be like this, I think you should seriously consider walking away.
When you marry, you want to truly believe you can be ‘happy ever after’. Sadly, it doesn’t sound like that with this guy.
