Hi,
That's a very delicate question with plenty of space to go wrong..... One has to be very carefull. There is not a clear answer / signal / sign.... it's more a combination of many tiny signs / signals / behavior..... or tiny minute changes in the body language (sometimes hard to detect). So my bast advice is: Go after your heart and intuition. Pay attention to his behavior and body language. Listen carefully to what he says and how he says it (and be alerted to changes..... tiny as they can be). Here is a short list: Wants 2b less time with you, less warm towards you, prefers to be alone or with friends on being with you, concentartes more on his works / hobbies, private jorneys without you, less intimacy, less kisses cuddlings, less open talks, looks less into your eyes, using words that are not warm and friendly as they used to be, going out less, less laughter, more "moods", starting to hide things from you (if it was not in the past)...... and many many more !....... One has to be a good sensetive detctive to "get" it on time......
Best regards,
