Maybe we can work on expressing our feelings more together? I have a feeling that we're the same- very strong and keep our feelings to ourselves- building walls around ourselves!
Do you think that maybe if you change a little (perhaps by expressing your feelings more) he might change in response? I just wonder if it's worth a go before making a final decision on what to do. If you still love him, it must be worth a little longer, although I know it's wearing isn't it....
It's interesting that she doesn't have any idea H is seeing you. Their R is based on untruths, and seemingly not so much time spent together. I honestly think the ring thing is a positive sign though- maybe he's waiting for a change/sign from you before changing himself. That he still spends so much time with you means he still has feeling for you in there, definitely. We just have to find the key to unlock him!!
