It all changed after we got engaged

Hi ladies,

Not else who else to turn to, so thought I'd reach out and see if anyone went through a similar situation

I got engaged to my boyfriend 1 month ago (the engagement wasn't a surprise because it was ruined by his cousin) and I just haven't felt the same way about him since.

I've been extremely sad and have no physical attraction towards him. I find it hard to kiss him, let alone have sex with him.

Is this an internal battle I need to fight? Or is there something wrong with our relationship that i can't pinpoint?

Prior to our engagement, everything was perfect and he was the man i wanted to marry. Now I can't look him in the eyes and say I love you.

Has anyone experienced this before? Who do you reccomend I speak to? He knows how I'm feeling, but there's not much he can do to help.

Thanks so much!
