Marriage on hold

i am currently living with my engaged bf and when we decided to get married about a a year ago and he bought a beautiful engagement ring for christmas showed all our friends and family everyone was shocked as he has never showed that much affection after his divorce 20 years ago. now everything is on ;hold he wont talk about getting married and no date has been set. we get along great as long as no mention of wedding plans come up and i do love him so much i have just left the subject alone out loud but mentally it has taken its toll i have read so much about communications with partners and let me tell you there are some nuts out there//some realistic advice would be most helpful
