Are these bad signs ??

My so and other talking less only about work.

We have been having less sex mostly he just wants me to suck him off, I know he’s not cheating just working a lot he owns he’s own business.

He hasent been spending any time with me or seem that into me it feels boring our relationship.

He buys me food and things I need and txts me roses and kisses but I miss the real kisses!

Also he hasent said I love ❤️ you much lately and I haven’t much either as I just haven’t felt it and want to say it when I’m really feeling it!

Help is it just me ?? Or are these not good signs he’s 45 I’m 31 if that matters at all and we been together 10 months and work together but aren’t together all day just talk on phone about work and in and out see each other.
