Step 1: Take control
Despite your girlfriend's demeanor, don't let this turn into a row, and take control of the situation. Boost morale by making an effort to make it look like you know what you're doing.
Step 2: Be confident, optimistic and positive
Remain confident and refuse to be defeated. Stay positive by concentrating on the good things about your predicament & explaining them to your girlfriend.
Step 3: Make her comfortable
Keep her comfort foremost in your mind. For example you may wish to give her your jacket, make her a shelter or offer her your lap for a pillow.
Step 4: Reassure her
Don't let yours or her imagination get the better of you. Soothe away any fears with logical explanations. You could also use humour to make her feel better - tell her how funny your grandchildren will find this story in 30 years time. Encourage her to talk about her hopes and dreams for the future that awaits you.
Step 5: Refuse to take the credit
Once your dilemma has been solved you can reflect on all the things you have done to put your girlfriend's comfort before your own and be happy in the knowledge that you truly are your girlfriend's hero!
