We only dated for 3 months but we fell deeply in love with each other. She seems like my soulmate and vice versa.

Her plan to study abroad and to be free and have crazy fun abroad was already set before we met -- she had already spent the money on tuition and flights.

However, it's scary that she is going abroad for so long and we haven't had enough time together already.

Is it a good idea to take a break from the relationship until she is back? Another option is to open up the relationship so that we can have casual sex with others..

Sexual exclusivity with long distance at such an early stage is highly restrictive and I'm afraid she will resent me for restricting her.
