Bump^^
I'm an INFP who has been dating an INFP for 6 months now and we are a bit older, in our very early 30's.
Our courtship has been....meteoric...to say the least! A shooting star. I walked around with a permanent blush for 2 months.
Things are starting to get more comfortable now, and I have noticed him pulling away a bit. We have talked on the phone every night since the first time, and what was frequently 3-5 hour conversations has started to reduce to 5-20 min. This is perfectly natural, but a change. Having been in lots of romantic relationships and being a student of personality theory, I am very in tune with what is going on between us and I see some potential problems that could occur if left unchecked.
I agree with the poster who said that there could be some competition, or one partner could get threatened by the other "stealing" the limelight. I was recently introduced to my partner's friends and family and while I know he is incredibly proud of me, I could tell their enthusiastic reception and praise got old to him very quickly. We also are both prone to depression and down moods. However, so far, we have been good for each other in that we know how it feels to be in a mood like that and we can help the other by being understanding. A big problem for us is mood transfer. If he is in a bad mood for an extended period of time, it can leech off on to me and I might be a bit down for the next day or so and vice versa. I have also found as we get more comfortable with each other, emotional communication is not flowing as freely. This again is typical for most relationships I think, but where he used to tell me most of whatever he was feeling and I could rest assured that there was no unspoken values not being met or resentment being built, now he is holding more back and I continually feel the need to ask him probing questions to ascertain if there are things existing that could foster resentment. In some ways, I feel this is a benefit to us, because I know my own heart so well I can anticipate future problems between us and hopefully address them before they become huge issues.
So those are the challenges we've faced so far. In closing, I would like to go back to the beginning and say that even though we have obvious struggles, noone has ever made me feel the way he has. Just by being himself, he has the uncanny ability to heal anything that is wrong with me. I bloom like a flower when we are together.
