Help please with fiance/marriage visa application

[Boosie]

Hi,
Please could you help me and my fiancé here? We’ve tried other forums and even immigration solicitors, but no one has replied except for an online solicitor who told us what we already know. We’re getting rather confused and upset.
We have a rather complicated relationship, my fiancé, Val, had a relationship before we met. She’s Ukrainian, and I’m a UK born citizen living here in the UK. She met a British guy and visited him on a visitors visa for 6 months back in 2011, she then returned to the UK in June 2012 after getting a successful marriage visa. However, her boyfriend at the time had doubts about the relationship and she ended it (the relationship) after only being in the UK for one week on her marriage visa. Now, she met me online in August last year, and to be honest we had such a lot in common, we got on very, very well indeed. Now, we want to apply for a marriage/fiancé visa, so we can get married here and start our new life together. However, there are a few irregularities, which the ukba would gladly pick up and give us a refusal, or as my fiancé worries – banned from the country. The problem stems from October, she came to see me while she still had a valid visa, although the visa was the marriage visa she was granted for her ex.
We’re worried because she said she was staying with her fiancé in his town, but she was actually here with me, when questioned at the passport control on entering and again in the visitors visa application. We got on extremely well together, she applied for another visitors visa in December/January to visit her friend who lives here in the UK, but because of her previous marriage visa and no job (she gave it up to move here when she came on the marriage visa) or reason to return to Ukraine after her visit (no family ties, children, job or children etc) she was instantly refused. In this application, she didn’t mention me on a list of friends etc. Now, this new application is difficult, we want to be honest and come clean so to speak, about meeting in October, but, if easier – create a new date from when we first met, in January for example. We wondered if there would be any repercussions after lying, but we have more evidence, photo’s etc from her visit in October. Also, I visited her twice, a week in March and about the same in April.
Please could anyone advise us what to do, whether to admit she was here with me in October, or try to make it look less bad by being bad and actually lying again and saying we met at a later date, and gather information required from this date instead of from Aug?
Thank you.

Past deception is not a reason for refusal, if applying under the Family of British citizens and settled persons category.

However, they may also consider 320(11).

Thank you very much for the reply Vinny.
So it looks like they could class it as "aggravating circumstances" depending on the clearance officers discretion?
