I would suggest you start by using something that helps re-establish trusting and open communication before you introduce a determined sexual like TUTH.
The IH/IS combo is what I’d suggest, unless any level of conversation is difficult, in which case I’d suggest you start with IO, then progress to IH/IS as things improve.
IH promotes trusting/sharing/caring communication but its drawback can be that it can go “too deep” - which may not be so good, for both attraction and the sort of things it might bring-out. So steering it with IS helps a lot to keep it on the pleasant/happy side of things.
My experience with stealth has been good so far but that’s usually using my own cover scent. However the new stealth oils have proved effective and long lasting for me, although testing is at an early stage. For sprays, I’d still suggest you stick with Neroli, which is a proven good diffuser and settles light by half an hour or so after application.
Depending on what turned her on to you in the first place, a status product like A314 might help remind her of what she’s missing and it will complement IH/IS very nicely (but not so good with IO) and sexual like TUTH can be added as needed. Late 20s are when women begin to tune-in to A314 on an attraction level and this really picks-up post-30. 
There are other deeper bonding/connecting combos that can be explored but I would see how you get-on with the starter pack first. They also often need prolonged periods of repeat exposure before they really hit-home.
Phero self effects vary widely between individuals - some get them very strongly, others not at all. Also, any self effects tend to be strongest on the first few applications and you adapt in time. So do give each product a run on its own first to see how you feel on them. 
As well as helping yourself via pheros, you will also benefit from a repositioning of your attitude/behaviour towards her. Don’t be afraid to step back and not be too willing to give it all her way. Often it is when a partner grows too used to you, starts to take you for-granted or becomes too comfortable around you that things start to suffer. So be ready to assert yourself when needed.
And if you are living apart, don’t hesitate to explore any other options that might come your way. Again, sometimes her seeing that other women still find you attractive can do a lot for her feelings towards you too. And you need a bit of fun/de-stressing to help get your own self-respect back in good perspective, even if you don’t initially feel much like it just now.
