They will want to dominate you totally to boost their own ego. If you dump him, you may have to get an order of protection from him. I heard about Colombian men here n there how they usually cheat and stuff.
There are very few exceptions to this and I say birds of a feather should stick together. but also heard they also can be very kind and supportive and other goood things.
Because you’re not a paisa chica, don’t expect him to pay for your meal.
Coming from an equal-rights country, he may expect you to pay for your share (mine definitely does).
Chivalry is not dead in Colombia and you can expect your Colombian man to open the door for you to walk through, pull out your chair at a restaurant and tell you how beautiful you look at the beginning of your date whilst holding your hand across the table throughout the evening.
