I'm now more confused than ever. My current relationship is very strong and comfortable and the relationship I had with my ex-boyfriend was very lively and passionate. Old boyfriends and girlfriends tend to resurface just when their exes are ready to make a commitment to someone else. Marriage is not about being swept off your feet. Marriage is a lifelong commitment to another person with whom you are compatible.
Marriage is about companionship, love, compromise, responsibility, and of course, good sex.
The passion for your ex-boyfriend is fleeting. Remember, he's an ex. There's a reason you broke up the first time. While I'm sure the passion and liveliness is what stands out in your mind, there are surely other aspects to his personality and your relationship that were not as wonderful. Try to be friends with your ex.
