Your feelings will fluctuate in ANY relationship, whether you've been with someone for four weeks or four years. =) Yes, being sick, stressed, etc. CAN affect how you feel about your partner. You may not want to commit as much time and effort to the relationship, and that can lead to your feeling apathetic or less "in love" with your partner for a short period of time.

I don't know if this is a temporary thing, or a sign that it's time to get out of the relationship and go back to being friends. The only way you'll know is to give yourself time to sort out your feelings. I would recommend waiting until you've been healthy for a week or so. That way, you'll know for sure it's just due to your illness. If you still feel uncomfortable with this relationship, talk to your boyfriend about your concerns, and see if you can rekindle your feelings for him. If not, then let him know, so he doesn't feel like you've led him on, and so you don't have to stay in an unhappy relationship for any longer than is necessary. =)
