My (32F) boyfriend (35M) has never had a relationship last more than 2 years. Should I be worried?

Throwaway account. My boyfriend and I have been together for 1.5 years, and we have been going really well imo. We see each other 4-5x/week, talk about long term plans, and our relationship feels healthy. Things like making sure to give each other space, communicating, and conflict resolution seem to just come naturally to us.<br><br>On my second date with him I found out that he's never been married before and has no kids. Which is rare for a man at his age imo. I wasn't too concerned because it seemed like he's never found the person that he wanted to take the next step with. But then I did some digging... I found he has a consistent track record of relationships lasting 1-2.5 years. (Mostly 2 years). <br><br>Some broke up due to his ex being too clingy (one literally showed up at his workplace) and some he broke up with because he got bored and/or found out that they were disloyal. I'm not worried about disloyalty. I'm worried about him just getting bored. He's the type to always want to plan dates and try new things, and I genuinely believe he loves me. I just don't want to waste my time if I know that no matter what, we're going to hit this 2 year mark and he's going to lose interest.<br><br>I feel bad for even considering this, because it feels like I'm judging him for being picky or having standards. But at my age and life stage, I really want to settle down with someone. I have talked to him about my fears, and he reassures me that he loves me and wants to marry me one day and that he's happy with me and doesn't feel bored. <br><br>But isn't that what he said to his other 4 girlfriends that also lasted for 2 years? I'm just not sure what to do. Any advice would be greatly appreciated.<br><br>TL;DR: My boyfriend has a track record of relationships only lasting 2 years and ending. I just don't want to waste time in case that happens with us.
