You were very brave to suggest taking a break so your boyfriend could gain some sexual experience, because you took a big risk in doing so. Now, it seems that that risk is not paying off in your favor, which was definitely a known possibility when you signed on for this break.
Your uneasy feeling is your not wanting to recognize that your boyfriend may want more than just sexual experience out in the world. He may want other relationship experiences, too. He has feelings for you and doesn’t want to hurt you, so that’s why you see him “mentally wrestling” with his life right now. But, sadly, if he doesn’t make a decision about your future together soon, he’s going to hurt you more than he realizes.
My suspicion is that this relationship is over for now. I know that this is disappointing, but I think deep down, you know it, too, and you wrote me for confirmation.
First love is hard to get over, and a 7 year relationship ending and coinciding with your graduating college and making a life transition from student to real life adult, makes it even more profound. But this is also an opportunity for you to spread your wings and re-create your life using all the wonderful resources you have. The break up will hurt a lot, but you will get over it, and you will go on to love and commit to someone who wants to spend the rest of his life with you.
I hope that helps, and I wish you good luck.
