Me and my LTR have been together for years now and we have two toddlers 2 year old and a one year old.

My question is if Im handling this correctly. So what this girl would do is, all day when I'm off work and we’re home together what she would do is like tease me throughout the day and always “seed” that we’re gonna have sex later tonight when the kids go to sleep.

She’s always like this off and on but now its been a few weeks she’s been doing this. She would tease me all day, shake her ass, try and randomly make out with me, grab my dick etc.

Then as you guys can predict night time comes around 11:30 - 12 and we’re putting the kids to sleep and then immediately she would go “ohh I’m tired too and my head/stomach hurts” and she would just lay down on her phone.

The way I USED TO handle this was just playing around with her on the bed and eventually just pulling my dick out and we get to fucking etc, sometimes with a little roleplay like “ohh we cant do this etc” whatever she likes it and i really don’t two shits so I play along.

However whats starting to happen is that her excuses every night become less “roleplaying” and more like LMR if that makes sense. Like she’ll tease all day and then as its leading up she would start to roll out excuses maybe an hour or two before we’re supposed to fuck.

So how I'm handling this now is for the past two-three nights whenever she starts to roll out the excuses I dont react emotionally i just start doing my own thing. I just leave her on the bed by herself and go into our second bedroom and just chill until im sleepy and then i go back into our bed when she’s asleep and just sleep. And she tries to cuddle me but i don’t cuddle her (i give excuses for that too like Im not in the mood etc but not in a butthurt way)

Then the next day I just mind my Business play with the kids a little and just do my own thing basically and pay her no mind. Now she tries to tease me and come up to me and try to kiss me but i either turn her down in like a “what are you doing?” Kinda way or just give her a dry peck and immediately turn and back to what i was originally doing. She’s just been getting ansty constantly asking me whats wrong etc and daying that she didn’t do anything wrong and even asked me if its because “she fell asleep and we didn’t fuck” I just played it cool and and said nah im just relaxing etc

Plus Ive been doing daygame pickup (how i met her) so i know i can always get another girl.

My question to you guys is am I doing the right thing and if not what should I change?

EDIT: Forgot to add to my first point. When I escalate past her “excuses” and we do fuck she had this “ughh ok fine lets get it over with” attitude EVERY TIME WE FUCK. Which is why im just commited to ignoring her flat out now.
