I am a pig and my male friend is an ox.

Mtwanas, the answer lies between you and him. If you both are able to do whatever it takes to maintain your relationship, then there is a chance that you can get married and make your marriage sustain. If any of you doesn't do his/her best, then it's possible that someone might stand between you and ruin your relationship.

You are a wonderful pair. However, That whether your marriage can last or not is really up to yourselves.
