Long but I need advice and that requires background:
My Fiancee and I have known each other for 7 years, been together for 4 (we were both dating other people when we met) and I just proposed in April of this year.
The proposal was earlier than I wanted because we are living in different cities right now (I am finishing graduate school and will then move to her city next summer) but she is a few years older than me and I could tell she was feeling family-starting pressure from her friends/parents and I am sure I want to marry her so I decided to go for it. The date is set for next September and the venue is booked in her hometown, etc.
About two months ago my fiancee tells me she has decided to start training for a marathon and has joined a training group with a friend of hers from work. Four days a week they go to their running club directly from their office after work. Initially I thought this was because she wanted to get back in shape for the wedding and give us something we can do together, which I thought was a great idea because I've always tried to get her into running but despite being a college athlete (soccer) she was never interested. I don't know who her friend from work is but I think she works with mostly females (it's a women's athletic sportswear company).
So I didn't think much of it at all when she started but now I am starting to get a little suspicious because a lot of small things don't add up. I don't want to be overly suspicious or accuse her of things, but can someone tell me if this makes any sense:
- First, they only run 4x a week, always during the week. She never meets up with this group or runs on weekends. Every marathon training plan I've ever heard of does weekend long runs but she has never done one (I see her every other weekend).
- I have volunteered to run with her on the weekends and she instantly shut it down ("You'll go too fast, I'm tired" etc.)
- I've asked to see her training plan, she says she doesn't have one, they just tell them what to do when they show up. I called the running store where they meet and there is a marathon training group that meets there so at least that part is true, but wouldn't you tell athletes what they were doing with a schedule?
- When I ask her where they ran or what the workout was she'll say vague things like "a loop past downtown" or "we went out to a trail" but never really describes them well. She doesn't seem to know about various paces or things like tempos.
- She doesn't look much different. Whenever I start running again after a break I notice my body changes after a few weeks (my calves get more defined, waist slimmer, etc.) Her body looks pretty much the same.
- Our sex life has decreased a little bit. Since we don't see each other during the week we used to have a pretty active sex life on our weekends but now she's been saying that she's tired more than usual. Running always increased my desire for sex so this seems off to me too.
She has never cheated before and seemed so happy about the engagement that I can't really imagine she is cheating, but this all looks kind of suspicious, right?
I should say that we have had issues with me being insecure in the past (she is much more attractive than I am) so I don't want to accuse her of something unless I am 100% confident or else she'll just say I'm being paranoid, but am I?
