wow that is very confusing and i cannot imagine how it must feel to be put in that position. The only advice i can give in regards to him is be honest….Have you weighed the pros and cons of how you feel for this man, is it real feelings or is it a comfort thing. I dont know how you to are with each other or what you two do together so i cant really judge you on that but what you have said, and the way it sounds is you are a shoulder for him to cry on. You are caring and being a true friend for him in a time where he needed someone. Is he still in love with his ex? Is he still missing her? does he still talk about her or want to get back with her or antyhing like that??. If things are getting a little more intimate then, instead of going in for the big kiss because it can either go good where he does kiss you back or he could push you away and well it will feel completely embarrasing, Maybe be honest and open with him and tell him how you are feeling for him and weather he is feeling the same way. Just try communicating with him and just ask him where do you stand because if its not what he wants well then you will have to have space apart because the longer it goes on for it will be harder for you to let go. And if he is feeling the same way for you then you both are letting each other know where you both stand in each others life, and well then thats a start… It all comes down to communicating and just being straight up and honest… Im not an expert neither am i here to tell you what i think is right, but i hope ive given you my personal opinion and advice and the option of seeing both sides and obviously the decision comes down to you. I can say though that something does need to be done or said to him but how you approach the situation only you can do.. No one knows him well enough like you do… Best of luck huni, go with what you think is right 🙂 x
