Thank you all for your replies so far it means a lot and I can totally appreciate what each and every one of you are saying.

Now I would love to speak to her about it on Saturday but I am not sure where to start as I cannot exactly comes out with "I notice you tend to say I love you less on your text messages, why is this?".

However I then play over scenarios in my head where I give a big lead in about how I sometimes get anxious and overthink and I don't want her to take it personally etc, but this feels like a big speech which again I am not sure if it would be the right idea.

The logical part of my mind also keeps telling me that she still "sometimes" messages it so must still feel it, but the overthinking part then hits back with the fact she has not not said it since tea time yesterday and makes me briefly think "will she say it again".

When I write all of these things on here they feel silly and I think do I need to speak to her about it at all. However when I think about them in my head they feel massive to me. From reading about it though I guess this is how anxiety does indeed work.

I also get the feeling in my head that I must immediately when I see her Saturday tell her I love her to ensure she will definitely say it back which again sounds silly.

Part of this ramping up more recently could be because of the fact due to a work trip we did not see each other this weekend so it is two weeks as opposed to the normal one week between seeing each other and I get silly thoughts such as if we are apart too long will she start forgetting about me or losing interest.
