Complicated Situation

[cantkeepcalm]

Hey guys. I really had no idea where to post this so I am posting here hoping someone can help. Long story short, my ex and I broke up last week for the second time. He left me and I have been devastated about it. Since the break up he has been pretty distant, but we have still been in contact somewhat. Yesterday we met up and he took me to lunch to apologize for everything we have been through and to try and put a truce between us so that there is no hatred or animosity. I could never hate this guy. I love him with my whole heart and I really appreciated the gesture. Although I am not 100% over him, I still feel like that provided me some closure. Anyway during lunch he told me that he still loves me, but he has some mental and emotional issues that he needs to work out on his own and he is just not fit for a relationship right now and I can see that. I know about all of his issues. I asked him if he still thought that one day when he is in a better mental state that we could be together and he told me it is a possibility. I asked him if he wanted me to wait for him or if I should just date around and move on (I love this guy so much that I am willing to wait for him to go through whatever he is going through). Of course he told me that in an ideal world he wouldn't want me dating anyone else, but he also said that he wouldn't dare request that from me. He just asked me that if I do date, not to rub it in his face and that he wants to know nothing about it. Anyway, I have been talking to this new guy for a few days and already I feel such a connection to him. I find myself wishing for texts from him now more than I do from my ex. I really am starting to like him and it is helping me get over my ex, but for some twisted reason I still can't help but feel like I am being unfaithful to my ex somehow. I am feeling so much guilt even though he is the one that broke up with me and denied my pleas to get back together. However I know he doesn't want me to date and I know for a fact that he is not dating anyone because he is not in the right mindset so I don't know what to do. I was with my ex for 3 years and still feel so much loyalty and attachment to him, but I really like this new guy. However, if tomorrow my ex were to come back to me, I would drop the new guy like hot coals. I think part of me is afraid to get to close to the new guy and move on completely. Someone help me figure this out please.
