did no contact then texted got no reply??

Ive not seen ‘t’ for 5 and a hlf weeks and no contact for 4 weeks. I sent a friendly text wishing him a fab time when he goes on his trip - theres no blue tick via whatsapp so its not showing he read it ( although I know you can read it in otherways) my logical side says he has read it but hasnt clicked on it - no big deal as its just a text and there was no need to reply. However I am still gutted. 6 weeks ago we where about to move into our new house - been together 14 years- to this? Do I leave it a fortnight and get back in touch? What to do when they seem to ignore you? Yet prior to this I know he was watching my movements on whatsapp amongst other things. When I sent the message he didnt use whatsapp for the rest of the night. He is he just not ready yet. Arrrr. I had such hopes
