According to CloUdiSm III remix - Eco-love cycle,
relationship don't stay stagnant even though people may feel
stagnant. Relationship rise and fall periodically.
Your cycle has probably reached growth. The relationship is
growing, but at a slower pace. It could be near the third stage, in
maturity, but I don't think it is there NOW, but would be there
very soon.
You must understand a trade off between meeting often and
talking on the phone. A couple must understand that
conversation is like resources - the more you communicate for the
day due to meeting, the less you will talk on the phone, for that
day.
What you are trying to do is to prolong honeymoon period or
stimulate richer growth - You may like to share this issue with
your bf, express to him your desire to spend quality private,
personal, 1v1 life with him on good regular occasions.
Don't be silly - he won't leave you LIKE THAT lar. Don't be
paraniod. Govern your relationship well. This is nothing wrong -
more communication is needed. 
Cheers
