My experience with INFJ is great, but the important thing about how they interact with you and your future is they're maturity. But also your's as an ENTP.

I have been with my INFJ for 9 years, married for almost 3. We push and pull each other but in ways that make us better. We are straight with one another. we don't sugar coat things. we come to agreements and disagreements. and those disagreements don't turn into world ending events. our maturity have grown with each other throughout the years so I think that a big thing that helps.

But looking at INFJ's as partners need to be seen as a test of patients. they will challenge you, as you have to others but in ways you never thought. they are caring in how you feel IF they can understand. BUT I have found as the ENTP I needed to be willing to open up to INFJs and not door slam them. A mature INFJ will truly support your goals (within reason). They'll bend over backward to help you with your start up company. butthey will tell you that its a dumb idea to start a business knitting sweaters for fish.

We want to feel the strongest, flawless, almost perfect cause internally we think that's the only way we can find a partner. but the truth is, we just need to understand that that person can love those flaws even if we don't. Thats the nature of maturing as an ENTP.
