Try to avoid confusing what is likely to be reality with what you're thinking, Yvonne.
He has obviously made (or is making) it as clear as he can how he feels for you and he is also under quite a bit of stress. Take and trust him at face value and go with that.
Easing back or taking a break without placing him under _any_ pressure will give you both some time out – that can often times be a blessing in disguise. As an example, when Pam and I were in a long distance relationship, we (like everyone else on the planet) would have disagreements. The time apart without communication allowed some clarity and strengthen the relationship.
So when he comes to you when he's hurt, do the caring thing as just a friend. You both will get through this.
