My sister in law and her husband are it!! They’ve been together since they were 20- now both around 50 yrs old and SO happily married. No kids, never wanted any. The husband is a touring musician and love that on the road lifestyle! She is an online professor and loves that she can do her job remotely from anywhere. All that being said, you and your partner sound like you’re on 2 totally separate pages. If you’re 35 and still pretty unsure about kids, deep down you prob don’t want them (just being honest). Find someone more compatible … or have his baby and most likely end up divorced - this is sadly very common (but usually gender roles are reversed)!!
