I am not sure that the "answers" or "confirmation" you are looking for are to be found on an internet forum such as this. It would seem that you are looking for some kind of reading, where someone might give you some detailed confirmation of whatever it is that happened to make you believe that Chris has contacted you "on a psychic level".(?) Would this have been a one-off specific event? or has there been more than one occasion to make you wonder? Did this occasion, or occasions entail some form of tangible, material occurence, perhaps unusual and uniquely relevant to Chris? You could always send out a thought to him (or even better - speak out loud, if you're on your own!) - and ask 'Was that you when such-and-such happened? If so, can you do it again to convince me, or do something else specific, give me some sort of confirmation ..."
etc. It's not such an easy thing for spirit to make direct contact with those still living on a one-to-one basis (hence the general need for a medium, a helping hand through which they can make their presence known and get their message delivered through)
, so it really helps them when the person they are trying to communicate with acknowledges that cntact - and it actually makes it easier for them to then strengthen that contact.
If you live in an area where you have easy access to a Spiritualist church or centre where walk-in demonstrations of clairvoyance / platform mediumship are held, it might be worth your while to go and sit in the audience of one or two of these sessions.
I do hope you get the confirmation you are seeking, and if/when that happens, I hope you'll come and let us know.
