Joe, no apologies necessary. It's a gutsy move to ask for help and opinions. What do you want from Jen? Do you trust her or are you allowing your desire to overpower distrust? Love pain is difficult stuff and it seems that it will never end, but it does. Be good to yourself and be respectful to Jen. Be honest to yourself and just as honest to her. If you will do this then it will become clear what your decision will be. Hanging on to a relationship out of desperation, even if there is still some love there, is a diservice to both persons. Best wishes for a lifetime of happiness to you, Joe.
