I tore my abductor muscle training for cross country marathon. It took six to seven weeks before I could run again but I took ibuprofen for a week then started massages and loads of forward and side lunges ice packs for a week and try hot water bottle packs all helps with blood flow to area.I don't think your injury is as bad as there was no way I could run on mine without intense pain.
Cross trainer in the gym kept me fit ( no impact).
Also get your girlfriend to massage all areas this will help with moral.
Find a four leaf clover and get some blooming luck. Sorry not much use but squats and slow one legged squats 10 reps x3 will help I had runners knee and saw physio he recommended this to me it worked for me. Again good luck
